Remember why uBlock Origin exists in the first place: Raymond Hill was fed up with the chore of all the administrative crap around uBlock¹. They wanted it to be a hobby and it started feeling like a job.

So it’s predictable they’d get fed up with that Mozilla review process and call it quits too.

¹ Which led them to hand the project to an unscrupulous rando that immediately tried to monetise it, leading Raymond to hate the outcome and having to decry his own previous project and ending up essentially where it all started but with a bunch of extra work in the middle.
