Proper, full blocking of ads and trackers. Just because you can't see most of them doesn't mean the network requests aren't getting through. And you're not getting a free and open-source extension. And you're not getting 3 extra bucks a month in your wallet, because those grifters made you pay for some pixels despite not contributing to the adblock lists their "business" depends on.

what do you mean? 1Blocker blocks network requests.

It might not block everything to the degree of uBlock Origin, but it does block network requests.
