It stands for Freedom, which is the original name of the architecture, or Free, in the GNU/GPL sense. The F does not stand for free in a monetary sense. You will have to pay for the F1 chip, just as you have to pay nowadays for a copy of a GNU/Linux distribution on CD-ROMs. Of course, you’re free to take the design and masks to your favorite fab and have a few batches manufactured for your own use.
