From an outsider perspective, I think Meta has been overhiring, meaning they have too many people for the economic downturn and for the product(s) downturn. Old school Microsoft was limited in staff because they insisted on giving everyone an office. Meta was really only limited by money, and even that wasn't a major limit.

There's likely a bunch of people who CTCI-ed their way into Meta. They're not competent and not motivated. They might as well be bank robbers, in it for the money and free lunches.

These people would be a burden on their team and other high competence staff. I think turning up the heat might weed them out. It's possible it'll have collateral damage, but it could well be that Zuckerberg realizes they should be getting down to their roots. If he doesn't act, the company will likely be synonymous with Yahoo. High performers will leave a company on its way down anyway.
