Unless they want to claim some side effect of working is part of the employee's compensation this lawsuit looks baseless enough to be an abuse of process.
Actual damages are practically capped around 3 months on the theory that you should be able to find a new job in that timeframe. And if you don’t, then that’s evidence you’re not actually qualified qualified and the termination wasn’t wrongful! And if Twitter is effectively paying 60 day’s severance then it’s even harder to show actual damages.
Now theoretically punitive damages are a possibility. I assume that’s what this lawsuit is hinging on, raising the however unlikely possibility that a jury might vote for punitive damages. That almost certainly won’t happen though absent gross malfeasance: think outright full blown macroaggression racism or sexism. Otherwise, well privileged tech nerds like tweeps just aren’t very likely to get a jury all riled.
Those who were put on garden leave have 3 months of pay to lean on while they search.
Those who were not, if they quit, their pay ends that day. They'd have whatever savings they have.
You asked what was stopping someone (who wasn't fired but who wanted to leave) from just quitting.
Now, kenjackson's statement is kind of generalizing from self a bit. He believes he'd want to leave in that situation and believes that most people share his ideals in this case.
And while it's probably not the case, it's also not the case that the number is zero.
There are valid reasons to stay in an undesirable situation until you can line up something better.
