If facebook can't 'control' the output because of AI or whatever as an argument, thats facebook specific.
Can google control its output? Yes for censoring etc. but Google shows you external self indexed and self analyzed content, Facebook doesn't do that. It has logged in users using their tools to create content and Facebook uses their internal algo to show whatever they want to you.
Facebook has nothing besides their social network. They care very little about a lot of stuff (after all they didn't care about fakenews and other things).
The metaverse was a huge waste of money.
Their AI Character thing is weird.
They cater to a lot of small businesses, thats definitly helping them.
But besides that? They have very little to do what Google, Microsoft, Apple and co are actually doing.
