Although I get your point, let's say you were working for a start up that was seeing ridiculous growth, and everyone knew that the growth was because you were the first, and you needed to keep smashing that growth to grab as much market share as possible before others copied and joinined in and potentially did it better. I'd understand the company wanting/needing dedication from the staff beyond normal, and in situations like that, I'd happily give a year or whatever of my life, but the rewards needs to huge and there.

Imagine working for Google when it was less than a year old, Facebook, tiktok etc.
I don't see it with twitter. The rewards seem to be "you get to work with Elon" until he might fire them because Biden performs better than him.
