Craig Wright has not proven that he is Satoshi Nakamoto
well, not publicly, AAR.
and the only one that supported that was Gavin.
False. Other notables include:
Jon Matonis
Joseph VaughanPerling
Ian Grigg

These are not mere irrelevant lightweights, though there are more than a few of those as well - perhaps less credible.
Some skepticism is merited. However, when you assert lies to make your point, it suggests you don't have any clue about which you are talking.
Now Gavin is part of the Cartel to promote Bitcoin Unlimited.
Really? What evidence have you of this? Or are you just making shit up again?
.... IF Satoshi comes back now, it would hurt whatever side he/she chose more than what most would think.
Perhaps. Hard to tell.
His return would effectively signal a return to a centralized authority figure
Doubtful. True Bitcoiners should not be swayed by any directive from Satoshi - to a true Bitcoiner, his arguments must stand on their merits.
