I took the attitude shift as happening when Lorenzo didn't obey team rules, it kind of shows he's not really a team player.
You should provide us with your list of premier class world champions happy to follow team orders, I can’t recall many off hand, not even Alex Criville.
I am a Jorge fan, but stopped watching the race in question because there was no good outcome for me, even Jorge winning if doing so harmed Dovi’s theoretical title chances. Dovi’s chances were mainly theoretical, and pretty much required MM to crash (I can’t recall if both Dovi and Jorge beating him would have helped, but if so Jorge needed to stay as close to MM as possible rather than concede positions). I consider it likely Jorge would have let Dovi through if his title chances became less theoretical, but we will never know. Ironically MM did nearly crash late in the race, but I agree with those who opined at the time that he was more likely to crash riding comfortably for position than contesting fiercely.
As I understand it one of their main points of difference was over who was responsible for the improvement of the Ducati bike; I tend to think it was Jorge more than Dovi, both at the time and using the retrospectoscope. The guy who indisputably did have something to do with the bike becoming more competitive, one Gigi, certainly wanted Jorge despite Ducati already having Dovi. Domenicali, the guy who eventually prompted Jorge to leave is also an ..... in general, whether or not his attitude to Jorge was justified.
From my position of eminence sitting in my armchair, or sitting in a cafe having my Sunday morning coffee, Jorge is (or was anyway, the march of time and injuries may be catching up with him as another Jorge fan in Furiosa has said) very much a (premier class) championship quality rider, while Dovi imo although talented beyond the dreams of ordinary men isn’t quite.
