Why would this happen? From the outside, it seems like Elon is absolutely decimating employee morale. See for example this thread from an engineer who has no beef with Elon and wants to see Twitter succeed, but still took the severance: https://twitter.com/peterclowes/status/1593458225533313025
At this point, the company was hemorrhaging cash. He had no choice but to stop the bleeding. It is a messy process and time works against you; mistakes will be made.
Nobody in their right mind would publicly support Elon right now because he's acting like a lunatic and therefore undeserving of support.
Regardless of what you think of Twitter's future prospects, none of these destructive antics make it stronger. Twitter could still be saved, but it could have been saved even easier without all of this pointless and public display of arrogance and incompetence.
If you burn everything to the ground and then basically hire a whole new team to work on a whole new app and platform, then your productivity has nowhere to go but up.
Once he gets to stabilize the cash flow, Twitter can provide a comp model to attract talent. About that, let's just say Geohot would not have worked for Parag, as an example. https://twitter.com/realGeorgeHotz/status/159295542717976576...
