"I'm sorry to see that my blog entry on recent controversies
over freedom turned into a thread about TiVo. But since TiVo seems
to be such a hot button, I would like to address that issue
directly. I made the point in the discussion that TiVo did not
license its hardware under the GPL (duh, GPL is a software license,
after all), or even a GPL-like license. So all the fuss about what
rights you have with respect to TiVo hardware is nonsense. Sure,

But you will void your warranty, and TiVo is under no obligation to
provide you with the schematic, BIOS, or anything else to make it
easy to modify the hardware. Having said that, let's cut through
all the posturing about what rights we have, and get to the real
issue here, which is what motivated TiVo to use a digital

software and run the modified version on a TiVo box..."
