I understand that. But multiple browsers have cloned uBlock-like ad blocking as their core functionality. For example Vivaldi, Brave. And they don't need MV2 to block ads, and use uBlock filters (easylist, abp filters, etc). So they block ads even if they don't support MV2 anymore.
If you understand that, then why are you saying we don’t need MV2. MV2 does more. It’s better.
We need MV2. But we can't get it. Google is stronger. So instead of fighting for MV2, I say we fight for another set of browser-specific APIs in browsers other than Google's.
