Safari gets pulled out fairly often as an example of why declarative APIs are fine for adblocking, but if you actually dig into what the adblocking ecosystem around Safari looks like, it turns out it's a pretty good example of why declarative adblocking isn't good enough. There are tons of hoops to jump through, the best adblockers on Safari are running separate desktop applications to communicate with their extension and bypass some of Apple's more arduous restrictions. Talk to the Adguard devs about whether Safari's API is sufficient on its own to make an effective adblocker.
The only reason why Apple's move got less criticism than Google's is because comparatively not many people use Safari, and most of us don't really care what the extension ecosystem looks like on Safari.
