I think the issue is less PR but more labor dispute essentially - the high end having greviances is rarer but it does happen. They can weather being just another evil corporation reputationally - they can't weather mass defections of expensive talent that may decide to go to competitors or go Traitorous Eight on them.

They have a pattern there of being forced to bend since at least the "memo-gate" and although they don't like it the math is clear enough to them. If employees are making money net it is rational to replace them if the alternative could make more money. Willful employees are an annoyance with a relative liability to corporate but their productivity gives them cold rational sway that says "just add it to the employee expenses section if you know what is good for you".

It isn't ideal for everyone - indeed it works because they are outliers. If everyone can do flawless brain surgery it no longer demands a premium no matter how difficult it is. It is in some ways more powerful than traditional labor - they organize because they need the company. Companies can decide to leave and out source to cheaper locales in response. Powerful labor has few equivalent alternatives. I say powerful and not scarce because mere obscurity can be subsituited for - powerful less so. If they could have already they would have. The companies need the high end and they know it. Just look at Hollywood movie budgets to the stars - they can ask for such outrageous sums because the alternative is worse in the current climate.

Of course there is a caveat - if they ever become obsolete they will be dropped quickly due to their leveraging. Things can be very fickle especially with advances that can metaphorically turn weaving from an apprentice-journeyman-master trade to a factory job worked by illiterate women and children.
