I think there's a much better case – practical and even legal – for 'WordAds'.

'Django' caused a pure collision with another community project: rude, confusing, time-wasting for keyword searchers.

'WordAds' fits naturally with 'WordPress', is non-identical, and far less likely to generate confusion or search collisions. And, Google's money gusher can defend itself if it there is a legitimate trademark complaint; similar for-profit competitors should push every possible avenue for attention. (It's not nice to step on the toes of a free community project, but it's often heroic to step on the toes of a near-monopoly.)

Heroism aside, it's still a little reminiscent of "OpenOffice" and "Office Open XML".
