Some important nuance is lost here. Matt Mullenweg transferred the trademark to the WordPress Foundation (which he is head of) and the foundation (again... Matt himself) in turn granted Automattic the exclusive ability to sub-license the name
commercially. This is the important bit.
What this means is that any "licensing fee" would be paid to Matt's private, for-profit, VC-backed company (and direct competitor to WPEngine) and there would be zero accountability for how it would be spent.
In practice, the foundation doesn't enjoy any benefit to owning the marks. It's all smoke and mirrors.
