What about 'Trusted Computing'? (Score 1)

Perhaps they're trying to prevent GPL'd software being modified to include TC features. According to this article: http://www.cl.cam.ac.uk/~rja14/tcpa-faq.html, such things could still stay within the letter of GPL as it currently stands:

"IBM and HP have apparently started work on a TC-enhanced version of GNU/linux. This will involve tidying up the code and removing a number of features. [...] Although the modified program will be covered by the GPL, and the source code will be free to everyone, it will not work in the TC ecosystem unless you have a certificate for it that is specific to the Fritz chip on your own machine. That is what will cost you money (if not at first, then eventually)."
