My goal was not to refute you, it was to offer a broader perspective based on decades of experience caring about the same things you seem to care about.

The words I used were "overly reductive". Yes, what your manager thinks is important, but so is the broader company culture and what you believe to be right. If the entire company doesn't value something and you do then you're fighting a losing battle and you should get out before your internal motivation is replaced by cynical survivalism. On the other hand, if the company does but your boss doesn't, then the trick is to keep your boss happy and work on the stuff that matters to you with the people that do care.

Keep in mind that managers come and go, if you subvert your own values and judgement simply to align with your manager, you may get a better performance review in the short-term, but in the long term you lose yourself and won't gain the kinds of leadership skills that are key to long-term success.

Often there are many times more concerns than just UX. Some of them real, other concerns manufactured. However, when the decision process is kept opaque, respect is kind of lost in that kind of environment. From experience, the people will never change either, but things can change when their start to die, retire or relocate.

It doesn't help to change company, when the same fads sooner or later starts getting pushed down there as well.
