Google and TikTok may seem free, but every click and scroll you make gets packaged into a "user profile" and sold to advertisers. Take Facebook, for example—it makes about $50 per user per year just from their data. In the internet age, if you're not paying for the product, you are the product.
This stats is not accurate. I have a Facebook account I created in 2012, just a name with a dumb email and some details that are not even correct, there is no way you will tell me that they are making $50 for every profile on Facebook. Perhaps, they make money from accounts that are active that post things on their feed and show up on the app everyday and that amount might be different depending on the location, not all countries advertise on Facebook.
If you look at TikTok, they don't advertise in some countries and without ads, they can't make money from such places. I think only US and some other few countries makes royalty from their content creation, that's because there are people that runs ads on the platform. No ads, even with personalized users, they wouldn't be able to make money from it unless they want to sell users data for some companies and it's a crime but I don't doubt it.
