Presumably referring to the mess that happened with uBlock when he tried to step away. That's why it's called "uBlock Origin" now; the original name was taken over by someone who then developed it in ways against Gorhill's intentions.
it was taken over by the same people behind "AdBlockPlus" which is a shakedown operation. They're allowing ads to be unblocked if advertisers pay them money.
The developers running it should be able to accept monies from the users of the product, especially donations. They have built something and are keeping the end users interests at heart while evolving the capability. It needs to be sustainable, else the intrinsic motivation will dry up.
The adblockplus model is extortion. They're not incentivized to serve the end user well, especially when their primary source of revenue is the advertisers the users are attempting to block.
The problem was that the person was essentially squatting on the name (in spirit; the name had been legitimately transferred) to gather donations for himself while not actively developing it. Then he sold it to the "Acceptable Ads" people.
