But I see your point, and certainly would like to see more constructive suggestions than mine.
Because I know very well how easy it is for people to think "oh, well, but that one little thing isn't so bad, when faced with bills to pay, or a raging boss. Many of which really aren't all that bad in isolation. Except it doesn't take all that many "one little things" before you have a total privacy disaster.
Alternatively a union can put pressure companies to never ask for certain things or to meet a standard for any privacy issues. Unions are usually seen with hostility in the tech industry, but they are just another tool; a union can be made for specific purposes, and ignore e.g. wage or anything else.
I agree with you, and e.g. in the UK we have the BCS, which does have ethical rules you are expected to know and apply (their membership is just a small proportion of the UK tech industry, though; in part because it is not prestigious enough for e.g. employers to ask for, while requirements for membership makes it a hassle to join for a lot of people), but at the same time it is not sufficient.
Especially give that a lot of things first become truly problematic in aggregate.
E.g. Developer #1 gets asked to ensure you pull in the phone contact list to tie your local contacts to your Facebook friends, to enable extra functionality (lets say a "call" button when you view their profile) that seems entirely benign.
Then developer #2 gets asked to match on phone numbers that have already been pulled in, possibly without even being aware that the phone numbers he is working on are not necessarily just phone numbers of Facebook friends but also unrelated contacts.
You can say that they should have verified, but often it is very easy to assume that it's fine, and not think about consequences. E.g. it doesn't seem so unreasonable to suggest friend-of-a-friend. The problem in the article is that it is not suggesting friend-of-a-friend but contact-of-a-contact, which is an entirely different relationship. But if you're told "here you can find a bunch of phone numbers for each user", build a "friend-of-a-friend" recommendation feature, it is not that strange if people assume it's actually "friend of a friend" - people like to assume the best.
Here's an example from my own past, that I did stop, but only at the last minute, when I realised what was about to happen:
And old boss asks me for a database dump from a "sort-of-still-client" that was leaving us. Nothing odd with that - they kept asking for more up to date copies to make their migration easier, and kept paying us for a year after they'd migrated their site in order to be able to continue to use their old reporting facilities.
So I prepared the database dump. Then I asked him how to deliver it, and he asked me to pass it to X. X was not the client, but someone in a new corporate parent. If my boss had instead asked me to deliver it to him instead of X, I'd have done it without further questions, and he would have passed it to X and the damage would have been done.
What X wanted to do was to mine it for potential customers. The almost-ex-client were not in any way competing with the new corporate parent, so it would not harm them was , but apart from likely violating our contracts with them, it was also a blatant Data Protection Act violation (UK).
My former boss thought this wasn't a problem because we were passing the data internally in the same company and we held the data in our system legally anyway. But the point is the data had been provided by the customers of our client for a specific purpose, and was handed to us for a specific purpose, and that purpose no longer existed. We certainly had not been given permission to use the data for sales. It was hair-raising when I realised what he wanted to do.
He accepted it when I explained why, but it was rather shocking that it took an explanation for him to realise it in the first place.
He was stupid to think his suggested use was remotely ethical, and that's the only reason I caught it: If he'd realised how unethical (and illegal) it was, and he still wanted to do it, he'd have asked me to provide the data to him, which I would have - that'd have been routine. If he'd asked me to put it up for download and provide a username and password, I also would have - assuming reasonably enough he was intending to pass that info to the client. Though after that incident I started being more sceptical about providing him with data without knowing the purpose first, and making sure the client had actually requested it.
Don't get me wrong. I have no love whatsoever for Facebook, and I would very much like to see a world where no Facebook does or even can exist. But there's a difference between recognizing the problems that result from Facebook's existence, and imagining Facebook and its employees to be deliberately inflicting such problems on people and thus deserving of threatening, even violent, action in imagined response.
Developers are not sweatshop workers beholden to the company store. They have a plethora of employment options. If they willingly choose to work for such a company, the case could be made that they have made themselves legitimate targets for having made this choice.
I might also counsel a certain restraint in your rhetoric, such that you fight shy of hyperbole such as likening Facebook to the NSDAP; ideally that would be your lookout and no one else's, but since we're arguing at least nominally on the same side of the issue, your statements reflect somewhat on mine, and I would prefer they not do so negatively.
It's not that. It's that in this very short life we have, it's not only not helpful (in the longer run) to pursue actions which knowingly hurt people for the sake of some perceived greater good (unless absolutely necessary) -- it leads one down a very dark path.
My solution? I'd prefer to educate people about the simple fact that most of these social media sites just don't do very much to improve our lives, are a huge soul-suck and time sink generally, and basically not worth the gargantuan amounts of time and emotional energy we invest in them.
So that eventually FB, WhatsApp and all the others will hopefully just die of starvation without a single shot fired (or employee being threatened or doxxed).
