Meta's problems are due to a lack of direction and very poor decision making from the very top. The Metaverse was a huge expensive failure, their core demographics are old people and their Instagram demographic is being eaten up by TikTok.
Zuckerberg is not an "ideas" guy. He had that one great idea back in the early 2000s (whether you believe it was his idea or not, he did execute on it) and everything since then has been acquisitions. Sure maybe they can wring out more "productivity" by return to office or firing their middle managers or whatever but so what? It doesn't matter how fast you can run if you are running in the wrong direction.
