Also blocking is not as good as intentionally poisoning with something like Ad Nauseum
Maybe I'm just lucky, but even this argument is quite ... meh
I.e. I can count the number of times I said "wow, uBO Lite didn't make this site usable but loading up Firefox with uBO and it worked fine" on one hand. At the same time, if I ever look and compare how much is actually getting blocked, uBO is definitely blocking way more. Doing a side by side compare of dozens of sites it becomes easier to see minor differences I wouldn't otherwise have noted, but may not have mattered as much.
You won't "feel" this in your day-to-day browsing, but if you're concerned about your data being collected, v2 matters.
I'm sure this will all change eventually though and YouTube has a loophole planned so ad blocking on manifest 2.0 is impossible.
It definitely helps that it's also a great (though imperfect) browser.
Fines are only the slightest punishment.
