AdWords Removing Affiliate Ads?

Indirectly by charging $10 minimum per click... I can't think of a single affiliate that can cope with $10 a click, so why doesn't Google just say they are banning "thin-affiliate" sites, rather than this psuedo-ban. According to one Adwords customer, a Google rep said:

Google is deliberately removing all affiliate programs from adwords listings. They had a quality team go through and rate their experience on a whole wide group of sites, including affiliate sites. The over-all score for affiliate sites was not high enough to pass their new guidelines therfore they are all being flagged and when found are being removed. Indirectly of course with the $10 min bids.
