Reframing someone's disagreement as them "struggling with something" is incredibly patronizing and condescending and dirty conversational pool.

No it's not. It's a validation of the fact that something is so frustrating they are quitting over it.

The idea that it is patronizing or condescending makes zero sense to me. It's a factual description.

Its framing the issue as something that should be fixed by a change in the mentality of Marsf, not by rolling back the changes.

No it's not. Where are you getting that? It's framing that there is an actual struggle, which is the acknowledgement that it's something they can work on resolving. Rolling back changes might be the answer.

I honestly don't understand where you're getting this cynical interpretation from. It's not in the words.
