Nah, there's a big difference between what and how much you're allowed to block in V2 vs V3 - the current status V2 adblock is way outside the range of V3's version.

I'd say V3 blockers can probably block at best 30% of what V2 can block. Which means it has to be selective. It essentially nuders the extension, making it worthless - an adblocker that only blocks some ads is not an adblocker at all. It's more of an ad restrictor, and in heavily monetized sites it might not even be that.

It has but i read somewhere its very limited and can be disabled by Google whenever they want.
