This is not a problem you can just throw resources at to solve. The problem is that some people will only categorized ads as "intrusive" if they play sound or take over control of the whole page. Others will categorize every ad as intrusive. Some people will categorize only ads that inject malware as "dangerous". Other will categorize all ads that have any form of tracking as "dangerous". The most straightforward way to serve both of these audiences is to block all ads. Few people are really going to complain that they see too few ads. Google is unlikely to do that for obvious reasons. So how do you satisfy people all both extremes of those definitions?
