It does represent freedom.
Kent can fork the kernel if he wants with all the fixes he wants in it and distribute it as he sees fit. This particular instance of the kernel (which happens to be original -- the upstream), Linus has to balance allowing some fixes other developers want to include versus a 'minor' release of the kernel during this cycle (because it is a minor version release, not a major one). Kent could then also stop other developers from contributing to his fork but then those people could just fork his kernel fork and do what they want.
You as a user are free to use any of them. You're even free to take Kent's PRs right now with everything done in the kernel at this point, compile it and run it yourself if you want. You could even market it as something and sell it all if you want for a profit if you can get the customers. You're free to do all of that. You can do it right now if you want.
