There are two different definitions of free.
Advertising keeps the internet free as in your don't have to pay for it. However there is also freedom and advertising doesn't help there at all.
An advertisement funded Internet is still you paying for your content, it's just built so that you don't feel like you're paying for it. Advertisement is not free money, and it can not be free money. It's for-profit.
So with advertisement, you're still paying for the Internet. We don't have a free Internet. We have an Internet built around businesses that make their entire business around psychological manipulation and extracting money from people without being noticed. The fact that people still push the myth that advertisement enables a free Internet like ad companies are somehow a public service shows how good they are at manipulation.
But ... I happen to be someone who REALLY DESPISES ADS ALWAYS
I'm not as "black pilled" as the comments that started this. My issue is not that ads try and psychologically manipulate people. I don't think that there is anything intrinsically wrong with trying to persuade someone to buy something.
My problem with ads is that they are annoying and distracting, most are this way by design, and they come at you completely unsolicited.
If there was a way that I could opt in or out of being shown ads in all areas of life, so that if I were interested in learning about new products I can, but if I'm not interested the ads can kindly fuck off and leave me alone ... that would be grand.
And that kind of exists. I mean, if I attend a ComicCon I'm going to a big trade show. I'm hoping that the show floor will have tons of wares and demos and such. I'm looking to buy. If I go on Amazon and start searching for products, by all means spam me with results related to what I'm looking for.
But if I'm trying to watch tv, or I'm on social media or in a context where I'm not actively looking to discover products that I might be interested in purchasing, I get downright offended and triggered when suddenly some dipshit character in a commercial is like: "look how ridiculous and annoying I am while using this product I want you to buy. If you buy it you can be just as moronic, obnoxious and annoying as me." In those situations I wish that advertising would just cease to exist in all forms all together.
Most advertisements are for junk that makes your life worse if you buy, but there are some that are useful.
Ads and the spying they depend on only trick you into thinking that you aren't paying for it when in reality, not only are you paying (often resulting with money coming out of your pocket) but you also never get to stop paying for it.
Once your data is out there, it will be used against you for the rest of your life. It never goes away.
It'll be passed around to advertisers, data brokers, law enforcement, lawyers, employers, insurance companies, scammers, retailers, and activists and year after year, decade after decade, every single person who gets their hands on your data will try to use it against you in any and every way that they feel will be to their benefit, and it will almost always be at your expense.
