chomping at the bit for some cheap impressions

1. it cheapens the advertiser's brand
2. it cannibalizes the ad network's premium inventory
3. how 'distressed' is that low end inventory (pages now showing ad council) really - e.g. lowering the page quality bar even further
4. there is no limit as to the amount of additional space that can and will be created if a webmaster can earn even as little as an additional $.005 CPM ;)
