Sure, and style points for the Derek Lowe allusion. I see why you think this, and probably agree more than disagree.
Three things that have influenced how I look at this:
* The revelation that Mullenweg was asking for headcount allocated to the WordPress project, not simply a cash payment. If you get a giant company rolling that is driven entirely off an open source project, it seems very reasonable to me for the open source project to use whatever leverage it has to get you contributing back.
* Mullenweg's argument that the norm for projects in "his" predicament to simply relicense to non-open-source terms; this seems incontrovertibly true, and also like it does a lot more damage to an open source community than what Mullenweg is attempting to do, which is to demand that a non-contributing company take his project's name out of their (marketing) mouths, and to stop using public services provided at the project's expense. WPE is in a position to mitigate anything Mullenweg can do here, so it's hard for me to sympathize too much.
* I was radicalized on this by working in security products during a time where it felt like dozens of funded startups were just picking up Snort and running with it as their core engine without contributing anything back, including proprietary stuff they built on top of it (and shipped in appliances, avoiding the licensing issues). I keep saying this is a "JABOG" situation, and I do believe that, but I have to remind myself of that to avoid casting one of these parties as the obvious bad guy.

Except Mullenweg has zero authority or ability to do so, without the agreement of all the GPL contributors. Mullenweg might argue this, but he also has been around long enough to assuredly know that this is neither the case, nor possible for him to do so. Apropos of anything else, he built WordPress by forking b2.

Isn't WordPress using GPL code owned by other people? He doesn't get brownie points for not doing something that's illegal.
