> But then: if they've been on notice for many months about Mullenweg being > upset about their use of the trademarks and lack of participation in the community (confirmed on camera, unless he forged emails), it feels to me like WPE --- a company with an 8-9 figure run rate --- should have been in a position to know what was coming with WordPress.org and how to mitigate that.
Matt's company owns and uses wordpress.com, so Matt's sudden concern about WP Engine using Wordpress' trademark does not seem very believable (or at the least massively hypocritical). The trademark issue just seems like a handy weapon to get what he wants. However, there are no good guys in this feud as you said -- only mud.
Again you're claiming it was "sudden", but it does not appear to have been sudden. Meanwhile: nobody seems to deny that WPE could simply use WordPress's OSS software assets to stand up their own services, including Mullenweg. But that's all open source gets you. It doesn't entitle you to trademarks or online services!
