I thought the motivation for the changes was obvious. The interpretation of the rules by the former moderator was so narrow, the community ended up banning people for having left-wing views and enforcing liberalism. There was no room for discussion, because if you had a discussion, the worst was assumed and you were banned. It went against the core ethos of the community. It seems that Kittenzrulz only wanted to bring the enforcement of the rules more in line with their spirit. There was never any wish to allow liberal points of view, only points of view from people further to the left like soulists and other schools of anarchism.
