One of the common private equity playbooks recognizes this - they’ll often jettison anything resembling an R&D department from a new acquisition, and run the company as a cash cow. If its market dies, so be it. Leave the innovation to the startups who are focused on it.
The problem with Facebook is that the founders have ambitions beyond their capabilities (apparently).
The private equity strategy of putting Meta into maintenance mode and focusing purely on their social media business would have been much better.
I think I left 10 or 12 years ago?
Zuckerberg had 2.5 good ideas: Facebook (shared), prioritizing mobile early, and buying competing social platforms with high growth
Everything else they've thrown big money at has been a dumpster fire.
The only plausible alternate reality I can see would have been one where US anti-trust was vigorously enforced and kept Instagram and WhatsApp from being bought.
But that would have required expansions of US anti-trust law to allow for more proactive deployment.
A nice hint for legislators to come.
