Just to add my thoughts to your Facebook point:

I don’t use Facebook much but I do have an account for the sake of keeping connected to distant family I’d otherwise never speak to again. The rare occasion I’m directly contacted and open the app to see what’s up, legitimately every other post, sometimes several in a row, is some kind of ad or sponsernd Post. Legitimately my entire timeline is one massive ad reel, I cannot fathom how people keep using the platform. Literally anything else would be better
