If you followed his months of mad ravings, he made it clear that Wordpress is not a true open source project. He has direct control over the project via Automattic appointments in the community, everything is designed to route through his circuitous network of shell corporations and trademarks (wordpress.org is fully under his control and he personally owns the Wordpress trademark - which the "project" licenses from him).

The only reason Wordpress is open source in the first place is because it's a just a fork of b2/cafelog and the original GNU license means derivative works have to be open source as well. (Lost in his moral crusade against WP Engine is the fact that he never really contributed to b2 besides just taking their code).

Matt made a big deal of transferring rights.

When the rights were transferred to the WPF, Matt didn't disclose that the Foundation was essentially just him, and the two other nominal members were effectively absent.

When the rights were transferred, and a big deal was made of this, "It now belongs to the WPF, which ensures that no commercial entity or interest can affect what should be a community project", there was no mention of how, on that same day the WPF silently granted a "irrevocable, non-expiring, exclusive universal commercial licence" to Automattic.

Throughout all of this Matt has conflated Automattic, himself, WP.com, WP.org, the WPF to whatever is most convenient to himself.

Matt says himself "I am WordPress.org. It's not a part of the Foundation", but you'd be forgiven for thinking so, given that the website resides on the Foundations AS network...

Matt doesn't want WPE's "revenue-sharing" license agreement to go to the community, the project, or the Foundation, though, he wants it to go to himself, via his private, for profit competitor.

Matt's claim, "My mom is confused and thinks that WPEngine is part of the open source project", is a deflection, and laughable coming from the man who runs wordpress.org as a "independent website" (that just happens to be running on the Foundation's IP addresses) and wordpress.com as a for-profit business. That seems just a little more confusing.
