Yeah, if you like tivoisation, you probably don't like the spirit of the GPL at all. Tivoisation is really a loophole that wasn't anticipated in GPLv2. It should not have been allowed by GPLv2, but it simply wasn't anticipated.

Vague is how the law is. It has to be vague, and the people who wrote the GPL have a good understanding of how judges interpret vague language. I trust them to have done a good job.
