This is what scares me about Metaverse. Initially I was like "Oh good, Facebook is blowing all of their resources on a bad idea everyone hates. I hope this goes badly for them!". Then I realized, the target audience for Metaverse won't have a choice-- it'll be a virtual office where people can work from home while under constant surveillance.
Last I heard, Mark spends ~$24M/yr. on his security detail. He's got very thick glass installed in his house. 2 foot thick, but I can't confirm that. It's not just bullet proof, it's RPG proof, or something. The optical distortions are quite real through that much silicon and plastic.
I'm not privy to the details on FB internally, but I imagine that the guys you're paying ~$67,000/day will keep you pretty cloistered from threats, either real or potential. Now, combine that with issues like the Dictator's Information Problem.
As such, I'd speculate that Mark doesn't really get to talk with honest people all that much. Mark ain't dumb, he knows it, but he also thinks all the stuff his security team is telling him is real too. A team that doesn't stay employed if the threats disappear.
So, in Mark's mind one solution is to 'air gap' the people from him via the metaverse. He's 'with them' in the same visual spaces, but his security won't be compromised.
