I tried looking up many online articles and didn't get a satisfying answer.
>b-b-but it's encrypted!
Doesn't matter. They know who you are, because your account is linked to your FB account (either directly or just by matching your phone number). Then you send them your full contact list when you install the app (have you tried using WhatsApp without the Contacts permission?). Then they can see metadata about who you talk to and how often.
Pulling up those advertising profiles, they can add to your profile: for example, if a good portion of the contacts you talk to daily have "interested in cars"/"republican"/"male 25-29" in their profile, there's a good chance you fall into those categories too.
Facebook actually updated their LIMITATIONS OF KEY METRICS AND OTHER DATA section at the top of their annual and quarterly reports[1] this year to say that "as a result of limited visibility into encrypted products, we have fewer data signals from WhatsApp user accounts and primarily rely on phone numbers and device information to match WhatsApp user accounts with accounts on our other products". Prior to 2020, did they not disclose this in their reports.

"We do not share data for improving Facebook products on Facebook and providing more relevant Facebook ad experiences.Today, Facebook does not use your WhatsApp account information to improve your Facebook product experiences or provide you more relevant Facebook ad experiences on Facebook. This is a result of discussions with the Irish Data Protection Commissioner and other Data Protection Authorities in Europe[...]
Importantly, WhatsApp does not share your WhatsApp contacts with Facebook or any other members of the Facebook Companies, and there are no plans to do so."

Yes, that's how I use WhatsApp. It sucks because all I see is conversations and calls from phone numbers without names.
But I don't trust WhatsApp enough to share my whole contacts list with them.
I would be happy to grant permission for individual number-name associations to be visible to WhatsApp, if that was possible. It's the contacts list as a whole I'm not willing to share; the people I'm actually talking with on it would be fine.
But no, we can't have sensible things like that.
Showing the numbers is very silly, because WhatsApp knows the name of every person I'm talking with. It has their name from the person at other end! But no, it has to use the Dark Pattern(tm) of showing numbers to pressure me into sharing all my contacts, which it doesn't actually need.
Trouble is, you don't have to. Your friends have already shared /their/ contact lists.
You're already a node in the network, even if you've never logged in.
this comes from back when truecaller was introduced and i had an iphone. saw permission to access contacts. never used the app, even today. same for whatsapp or facebook. call me paranoid, but i don't want being "linked". same reason i dont have a google account and even though i have been using an android device for the past 2 years, there is no account and i use something like aurora store to get apps. works decent enough
Not to be pedantic about an off-hand comment, but yeah, works fine, AFAICT. I'm not even a "pro" WhatsApp user: I use it strictly for the one social group that didn't think SMS was good enough. Meaning I didn't have to know the secret incantation. I'm sure I was asked about contacts, to which I assume I said "FB? Hahaha, no way!" And if I go to the Status tab, it sho'nuff complains about me not uploading contacts and if I want status of all my WhatsApp peeps, I need to upload contacts.
Yes. It works. Reaching out to new people is a PITA, as you have to append their phone number to a an api.whatsapp.com/send?phone= URL and open that on your phone, but it works.
For example, people like my startup (https://www.zoko.io) provides software that enable folks to run any business on (only) WhatsApp.
WhatsApp would make money by - charging for certain types of messages sent via the API (already doing it) - from ads on the WhatsApp, Facebook and Instagram Platform that click directly to WhatsApp.(already doing it) - enabling payments via WhatsApp Pay and then take a cut of the payments. (coming soon)
I am amazed by the things that my customers do with WhatsApp - like Fintech companies who provide loans to Uber drivers via WhatsApp, OR Fertility Clinics that dole out professional advice on how to make babies, via WhatsApp.
WhatsApp is just getting started! Remember when the internet was free, Google showed up and became a toll collector for doing anything on the internet? Just like that, WhatsApp is the internet of the #nextbillion people. WhatsApp, if they play their cards right, could become the "toll collector of the internet for the #nextbillion". I am literally all in, that it will.
Why then? Why not any other chat app, or even messenger with far greater reach and just as many resources?
In fact, Bolsonaro used WhatsApp spam as part of his election campaign strategy[1].

It was pretty much the days of AIM and MSN. When the rest of the world was on MSN. US was still on AIM.
Without the China Market WhatsApp has 1.6B user.
Outside of WhatsApp (2 Billion Monthly Active Users), Messenger (1.4 Billion MAU) and WeChat (1.2 Billion MAU) the others stand little chance of building and benefiting from being a platform.
Setting aside WeChat and China, if you now look at the next billion users who are going to be using the internet for the first time, WhatsApp is the lens through which they see the internet - they communicate, consume news and entertainment, buy and sell things, get medical advice, even fall in love via WhatsApp.
In India, where a significant portion of that #nextbillion are gonna come from, Messenger has ~100M users and WhatsApp has ~500M MAU. Similar multiples play out in "WhatsApp first" markets like Latin America, most parts of Asia.
Case in Point: Even though it had nothing to do with our business, we recently helped hack together a solution to conduct two, 20-question, exams for 100K students in an Indian State. Simply because every family had WhatsApp (and nothing else). Messenger simply doesn't have the reach in the emerging world.
The app used to cost €0.89 per year (which I guess was $1 at the time).
I'd be surprised if Facebook had bought WhatsApp looking for revenue. Even if the service is operating at a loss, it's still providing FB the messages (at the very least, their metadata) and personal data of two billion people.
By using WhatsApp, you become their product, and they are making money with you.
WhatsApp could have provided services like Facebook or Instagram but cost a small amount of money each year. Maybe it would be per-user or maybe it would be a sponsorship, like what Discord is doing. Sponsor the local neighborhood group for $25/year, your high school class forum for $100/year (so you can show everybody "you made it big").
The key to doing something like that is network effects, which WhatsApp had in spades.
Probably it's inevitable that they would have descended into advertising and tailoring the site for advertisers instead of users.
But WhatsApp on itself doesn't cost much to run. They had 1B user and was running it on 50 Big FreeBSD Box. With a tiny engineering team. And that was with Hardware and Software from 6 - 7 years ago. Modern Hardware with all the BEAM VM improvement would made it even lower. ( Kind of Amazing if you think about it )
They had to switch to Linux once they were acquired by Facebook to keep a common platform.
I guess indirectly maybe they acquired some more Facebook users although I suppose most people who had whatsapp also already have a FB account.
My guess is that they always wanted to turn it into the western wechat.
Encryption is a shady topic, and there is a realistic chance there is a backdoor in the methods WhatApp uses to encrypt content, history has shown this is realistic.
Governments have done way worse things.
