I totally get the point you're trying to make (and don't even disagree) but I think the analogy isn't quite right.
I'd actually be surprised if I got robbed at a mobbed-up restaurant; my naive understanding was that they actual put a lot of effort into keeping places like that above-board so they have legit businesses to attach their name/revenue/employees to, while still retaining muscle in case a rival tries something. It's arguably one of the last places I'd expected to get robbed outright.
It’s like when you’re having dinner at a restaurant owned by the mob and act surprised when the owner pays for your meal because “you look like such nice girls.”
Sadly there's a bunch of interesting communities on there that aren't really available anywhere else, plus some of the competing platforms are even worse just in different ways (though their ads are for sure better).
It’s like having dinner at a restaurant that you know is owned by a mafia boss and then being surprised when you get robbed while you eat there.
