If that were the main goal why not just ban them from the extension store? Or why allow manifest v3 extensions to block requests at all? Ad blockers still work and this did not kill off any of them. Just forced them to change some of their functions. I don’t doubt the executive overlords are happy about the turmoil that this has done to ad blockers but they would be pissed if that was the only or main goal of this as there are still loads of effective adblockers about.
