This doesn't necessarily mean Fedora Core won't be developed anymore...
And for governing Fedora Core, the company will rely on the Fedora Project Board instead of the foundation. The board includes five Red Hat employees and four outsiders.
It's just a business move or some such jazz on Red Hat's part. Don't confuse the Foundation, the Project, and the distribution.

There goes Redhat again, doing things as they want to regardless of what the REST of the community is trying to accomplish.
