I think this will be very beneficial to non-savvy web-users who may be tricked by misleading ads like the download buttons, and the like.

Ads aren't really a problem for me (and I am guessing a lot of others), it's bad/misleading ads like pop-ups, auto-play video ads, etc. I think the idea to block ads that do not follow an established industry standard is definitely a step in the right direction.

Savvy users will continue to use 3rd party ad blockers- no change there.
