Bollocks and hallucinatory nonsense. The trademark page had made it abundantly clear that use of "WP" was not protected by trademark and only made it an issue ex-post-facto when Matt decided one day that he didn't like the competition. The trademark claims are bollocks, nonsense, bogus — entirely without merit.

If you don't like your open source work being used by others to do for-profit things then don't license it as GPL or don't open source it to begin with. You can't retroactively come out and complain after the fact once you've already given all your IP away and made it abundantly clear that "WP" isn't a trademark, and BY THE WAY the jurisprudence on trademark law makes it difficult to even try to claim a trademark or servicemark from two letters put together!
