People should stop quitting as a moral protest when companies go against their principles, and instead stay in the role and mess up the internals.

It's quite presumptuous of someone without detailed knowledge of what's going on to second-guess someone who made a hard choice like this.

Sabotaging one's employer is also an ethically problematic choice to make. Imagine someone in your employ were to decide you were a 'bad person', say it was your lawyer or accountant...

Pretty sure that is a criminal act in most jurisdictions. Maybe not felony level, 20 years to life criminal, but criminal. Also you'd be de-facto unemployable after that. Not many folks in a position to just retire to the golf course for the rest of their life on a whim
