Let's go with the definition that's in the announcement itself.

Ok. So this definition deliberately obfuscates the difference between a project that *requires* a proprietary add-on, and a project that simply offers the ability to interoperate with existing proprietary software or hardware. I do not feel that your definition of Open Core is useful or widely accepted.
But let's follow this definition and see where it leads us. Are any GNU projects actually "FSFLA Open Core"?
Consider Gimp, the GNU Image Manipulation program. Gimp has features that allow it to run under Windows. Is Windows Free Software? No, it is not. Does running Gimp on Windows offer features that are not available if Gimp is run on other operating systems? Yes, it does. Certain printers, tablet input devices, and other hardware only have Windows drivers. By using the combination of Gimp and Windows, the user gains additional functionality. Therefore, Gimp is "FSFLA open core". Shock, horror!
The fact that you can run Gimp on operating systems that are Free apparently doesn't matter to the FSFLA. You can use the Linux kernel without binary blobs, too. The fact that the folks behind Gimp don't encourage you to use Windows or profit from Windows doesn't matter at all. Linus doesn't encourage or profit from binary blobs, either. The fact that Windows is an operating system, and Gimp is an image editor-- the "mere aggregation" of two unrelated products, as copyright law would have it, apparently doesn't matter either. Binary blobs loaded on firmwares are not derived works of the Linux kernel, either.
By this definition, any program that interoperates with proprietary software in any way-- any program that runs, or could be run by some "community member or distributor" on a proprietary platform, is "FSFLA open core."
Therefore, I claim that *all* FSF projects are open core.
Even GNU Hurd can be run inside a proprietary VMWare virtual machine. You will gain additional, premium features by doing this, like the ability to debug kernel crashes while running other programs on your computer. If you like, I will ship you a CD that contains both GNU Hurd and VMWare, hence tainting it forever in the eyes of the faithful. Are we done now?
