I don't think any of the mainstream blocking plug-ins claim to just be ad blockers. E.g. The first line on the uBlock origin Readme:

> uBlock Origin is NOT an "ad blocker": it is a wide-spectrum blocker -- which happens to be able to function as a mere "ad blocker". The default behavior of uBlock Origin when newly installed is to block ads, trackers and malware sites

Any third party scripts tend to fall under "trackers" (stuff like typekit, disqus often gets blocked by default as well), something that just burns your CPU in the background without approval could be classified as malware.
