It seems I'm in a minority here, but I was never comfortable installing any adblock extension because the existing request blocking API means that the extension would see all web traffic generated by me (including private URLs that are otherwise not known to anybody but me).

I personally feel that now with manifest 3, I can actually install adblockers since the newer APIs do not share all my web traffic with the extensions.

Can somebody explain why removing blocking API was overall a bad decision by Chrome?
