I wouldn't assume it has anything to do with them being an adwords advertiser.
The "made for adsense" part of the TOS is one of the most vauge and open for interpretation of the publisher or adsense team.
They may have a million other greedy or totally angelic reasons that this site is okay with them. For instance, in all its ugliness, it might actually produce conversions for the advertisers that appear on it.
