Disagreed. Content blockers are "dumb" as they just provide a list of URLs/regexes to block, which doesn't always work and doesn't allow behaviour-based blocking like "dynamic filtering" that some Javascript-based adblockers have.

Sure, it's technically possible for a JS blocker to use more CPU, but 1) it's a trade-off the user should be allowed to make (I'm happy to sacrifice some CPU in exchange for better ad blocking and privacy) and 2) I never had a case where a JS-based blocker noticeably impacted performance.
