It'll be interesting to watch this play out. I know ByteDance has been slurping up some Meta talent, and you don't want someone you lay off to build the company that eventually kills you.
If you buy into the premise that Meta was holding talent just so that other companies couldn't hire them, no longer is, and ByteDance has since picked them up then it stands to reason that ByteDance would be ready to shed the no-so-talented stand-ins they were using previously.
