Good stuff. Of course the apps *with* it already tend to have tons of downvotes mentioning the annoyware, but it saves people some research I guess.
Hmmm...I wouldn't jump to that conclusion too quickly.
The new policies seem to control for ad quality instead of the functionality of the ads, hence "ad context" in the new policy. Ads that mimic system notifications like "battery levels" and "messages" probably will be screened.

We may not get that much spam any more, but the formats of the ad probably won't change much. Airpush and other networks should still be monetizing devs.
