The whole point of the content blocking API is to protect the users privacy. Without it, the plugin gets to see every single web page you visit, and its contents, and could do anything with that information.
I've been using 1Blocker which, while not free, uses the API and seems to work very well. (And can sync your block settings with the iOS.)
Agreed. Content blockers are also not executing js code for every resource the page tries to load: it's just the defined blocking rules that get processed.
