MV3 DNR redirect is notably lame though, instead of replacing the response it generates a real redirect which breaks for example replacing the service worker response. But could MV2 webRequestBlocking replace the response? Well of course not.
So far I'm able to block everything I want, but I mentioned replacing the response body because this is the only way I could modify or even inspect the service worker.. I think this vector could help circumventing ad blockers, but again - it would only matter if there were ads I'd not be able to block.
When it comes to distribution, firefox sucks because I can't even run my own extensions there, my distro doesn't package firefox developer edition so signatures are required. In contrast, Chrome let's me load unpacked extensions without any problems.
Just observe this thread. It's a tribal moment, an occasion for a consumer to reassure himself that he has the right philosophy, uses the right product and rightly hates these other things that deserve to be hated. The fellow believers can upvote each other and downvote any empirical observation which threatens the faith.
