Ordinary people use it to try and talk to their friends, while being bombarded with shit and exploited.
They also use windows that do the same thing, and probably are used to being treated like that in exchange for free stuff.
It's just we who know tech that thinks it's absurd to allow ourselves to be treated like that, by people who are awful and rich.
I think it's a bit strange that we call everyone a troll these days though. Since when is it trolling to just state your opinion? Trolling was supposed to be when someone intentionally posts something to upset someone else.
It's very hard to actually know the difference unless it's a stupid poster who does it over and over again.
