OK, sure, but what are the actual, real-life consequences of that?

I don't see any ads online. So ad-blocking still works. What doesn't work?

only ads on big sites or ads by big providers are blocked

This is false.

Not part of any adblocker. Some, like Ghostery, have a separate mechanism to auto-reject these. I switched from uBO to Ghostery because uBO wasn't doing anything against those.

data mining and hardware fingerprinting cannot even be thwarted anymore.

That's not an adblock feature and there are hundreds of other extensions that handle that, like PrivacyBadger. Ghostery says it also handles trackers, but I haven't verified that.

I would rather see ads (topic based) than give up my privacy, and the complete uBlock Origin is very useful for privacy too.

Look up tools made specifically for it, then. Also: privacy related stuff is not affected by Manifest v3, no?

Well, considering I'm using a different adblock and I just... Do not see any ads on the web, how do you measure the efficiency of uBlock to be better? Resource consumption?

Eye-dropper and HTML cuts are not affected by Manifest v3, no?

Ghostery does the same stuff. Granted, it can't cut out HTML elements as you see fit, but that's a feature I haven't needed in over a decade.

It still blocks ads, what else does it need?

Is it? I don't know. I know it's the most recommended one, but I've tried uBlock, AdGuard and now I'm using Ghostery, and I honestly don't see a difference.

Yes, that's my point. People are crying here over uBlock, like Google killed their family dog, but clearly it's possible to have the ad-blockers work perfectly fine even on Manifest v3.

have a million prompts all over zillions of sites”.

I'm using Ghostery to automatically reject all of those. They pop-in and almost immediately disappear.

Define "lower efficiency", please.

Other adblocks still work. I’m using Ghostery on Vivaldi (Chromium-based) and it works perfectly fine, including blocking ads during YouTube videos.

No idea why uBlock specifically is being blocked, but it’s not like you can’t have an ad-blocker anymore.
