This situation is a general description that actually fits what TiVO has done. The difference in the TiVO case is that you (and everyone that thinks like you - ie: believes that the "tivoization" language in GPLv3 is good) equate "replace entirely" with "modification" when, in fact, the two are entirely separate acts. > > By using GPLix as part of their boot process along with their > > non-GPL BIOS, they're subverting the freedoms that the user should > > have in being able to control the entire boot process. > > You're pushing the "freedom to change" too far.

I don't see how TiVO has done this. They have placed no restrictions on *modification* at all. What they have done is placed a restriction on *REPLACEMENT* of the program. If you're going to argue that "replacement == modification" then it is an *easy* argument to make that every time someone *replaces* linux with a proprietary system the proprietary system magically becomes GPL'd. And no, this isn't a logical fallacy on my part. It's on your part - all I've done is take the logic you have provided and extend it to cover a different situation.
