90% of the ads right now, but its trivial to design adtech so its only possible to block a tiny percentage of everything with only 50k rules.
(register 50k domains, use 50k different subpath/subdomains and mix content+ads on something like youtube where you cant wholesale block youtube, etc)
This means they anticipate Google to target the Acceptable Ads program.
Originally I thought 30,000 rules wouldn't be enough to cover things, but according to this research, only a couple hundred rules are enough to block >90% of the ads: https://brave.com/the-mounting-cost-of-stale-ad-blocking-rul...
So maybe there's another limiting aspect of the declarativeNetRequest API I don't know of.
