In theory. In practice, Manifest v3 (the changes to adblockers) will be implemented at the C++ level, meaning you'd need to fork Chromium in order to avoid it. I would be surprised if Brave even had the engineering power to do that. Microsoft perhaps, but I doubt they actually will.

I think the parents comment's argument is that since it's based on chromium it also can eventually be forced to acquiesce, so any chromium-based browser is just a stop gap solution.
