Last time I checked, the job market is free and people are allowed to quit jobs that don't suit them. Employees are also allowed to organize themselves and act in unison.

Back in my day, if a job didn't suit our preferences, we quit and got new jobs that suited us better. If the old employers didn't like it, they'd have to come up with better offers. Why would you expect the aforementioned ex-Apple employees to do it differently?
