It certainly does not require FOSS users to purchase a license. There is already a shim loader signed by a MS-recognized authority, which ships with a signed copy of MokManager, which lets you register a "machine owner key" of your own choosing. You can then use that key to sign kernels for your own machine, or for anyone else who wants to go through the on-screen enrollment step to trust your key.
No additional money has to change hands between anyone, and no additional permission needs to be granted from Microsoft to anyone. (You have to get the permission of someone with physical access to the machine during boot, but if your goal here was FOSS users controlling their own computing, it's a good thing that that permission is required.)
