That's an asshole take.
Everything I've read is that Twitter is working its remaining engineers to the bone. Job searches can be extremely draining, and I can imagine many Twitter engineers don't have the energy remaining. Add to that mix visa and immigration issues, and I could totally see people getting trapped there.
This is what I think happened:
- few companies are willing to go through paperwork to sponsor visas. Old Twitter was, Musk Twitter probably isn't
- Musk inherited a bunch of visa-sponsored devs from old Twitter, and they will have trouble finding a new h1b sponsor to transfer
- those are the devs that cannot negotiate better salaries or leave easily
Basically Musk's Twitter's lights are on thanks to those employees. And whether they are good or not doesn't matter, they can't leave either way, job market is hostile
