Have you thought about licensing future additions to WordPress under AGPL? I believe it can be done [1]. This will disallow private forks and require companies to publish any changes they make.

I suspect WordPress will be GPL forever; it's a lovely license, and I enjoy publishing work under it.

How would this help? This isn’t at issue.

It would disallow private forks of WordPress (require them to share the modifications) but I don't know whether WPEngine and other hosts have any private modifications or they all use stock WordPress.

		The problem we have isn't that they have some amazing code they aren't sharing with the rest of the world.
