It doesn’t matter what he thinks he’s doing (my belief is that he’s just frustrated that someone else is profiting more than he thinks is “fair” and is using everything else as a cover, but maybe he does actually believe WPE is causing harm).
But here’s the problem I have with the whole position he’s taken. If this were actually about “Wordpress the project/community” the payment would be to the non profit not his personal for-profit company. If it was about trademarks, he should not have made the prior claims that the trademarks were not the property of his for profit when they functionally are. He would have not misrepresented the non profit as an independent entity (a fiction demonstrated clearly by the requirement to compensate his for profit).
if WPEngine is not contributing a “fair” amount to an open source project that sucks, but that’s always a risk if you want to build a for profit business on an OSS basis. But you can’t then unilaterally and retroactively change the rules later on, and act like it’s a “protecting the community” nonsense. You sure as shit don’t get to just engage in explicit extortion.[1]
Again, maybe wpengine was not contributing a fair share back to “the community”, but that’s just how OSS works, not everyone is a contributor.
[1] something I’ve found myself wondering about: my understanding is that under the law a contract signed under duress is not valid. Given the threats Matt was making, if WPE had signed it, would they be able to then go to court and say it was not enforceable due to the threat being leveled at them?
