You make it sound like everybody at Meta works in the ads department.
The only exception is people who’ve managed to sneak their way into positions where they don’t contribute anything to the company. Those people are doing society a favor by wasting Facebook’s money.
The whole Metaverse bet at Meta is also plausibly a 10s-of-$b bet that isn’t going to drive the ad flywheel, though I’m sure they hope it is. My impression is Zuck would be ok with just having a VR platform even if it’s generating revenue from not-ads.
