There is a major hole in your ad hominem and conspiracy theory. Gavin willfully gave up his power in Core out of principle to further distribute development.
Great leaders do not desire power. He gave up his leadership position in Core out of principle only to have Core turn against him to disallow the changes he wanted to implement. This reminds me of the story of Cincinatius, who was a roman dictator who also freely laid down his power, this should be considered admirable.
I should not have even responded to such a silly post, however that was to glaring of a fault in your reasoning not to point out.
He didn't give up anything, he never had "control" over the Bitcoin Core code. No one does.
In practice Wladimir had been the actual maintainer of the repo even before Gavin's announcement.
The announcement stemmed from Gavin's inactivity in terms of contributing code & ideas, nothing more. He more or less realized the project & state of the technology was now out of his league.
