I'm a bit astonished how often I see this kind of thread, even here. It's like when people complain about FOSS apps charging subscriptions or standalone fees. How many times does it have to be pointed out that piracy as an activity does not define piracy as a movement or a collective?
I'm certain this simplistic "piracy = not paying for stuff" take can only come from a kind of ignorant individualism, one that lacks any structural analysis of why, when, and for what content people turn to piracy (and why, when, etc, they stop).
It is an interesting project, not sure where it goes. The title is deeply misleading though. The features of ReVanced make YouTube so much better, whereas this project doesn't seem to be about making YouTube better so much as circumnavigating YouTube for the comment boxes and as your hub to creators. They seem to be doing different things.
