What? I don’t buy that. Apple is criticised for being a walled garden, I don’t think I’ve ever seen strong criticism toward Facebook for that; I assume you’re conflating them somehow.
Facebook was criticised for a few things; constantly changing the UI, selling personal data (although this was mostly opaque and treated as a rumour that wouldn’t harm _you_ really) and being a monopoly.
Now it’s criticised for aggressive targetted advertising, which may have had a hand in polarising people and even allowing some companies to highten fear and aggression to the point where it subverted democracy in some nations.
It’s also criticised for stifling free speech and siding with governments de jour in heavily censored countries like Iran.
I mean. I was an adult using Facebook before “the social network” movie came out; but maybe I misremember?
