I think people are failing to understand that Google wants to start MV3 from a more secure and privacy protecting state and figure out how to incrementally add capabilities without compromising that.
Making the tradeoff of reducing your security / privacy / performance for more freedom is not the right call for most people. Extension authors have abused their freedom so it should be taken away.
Have you actually tried using uBlock Origin Lite or Adguard on MV3? I've used both and they have worked flawlessly. Currently I prefer Adguard because all websites are opted-in to cosmetic styling by default.
I can't, because MV3 is not in my version of Chromium yet. But I don't need to: I know exactly how MV3 works, I have experienced that approach on iOS and it barely works for the most simple kind of ad-tech. Calling it "flawless" sounds like outright FUD to me.
