According to an ongoing debate over the GPL version 3, he does. How can this be, since Linus Torvalds, creator and chief architect of the Linux kernel, knows about software freedom and free software? He doesn't have a problem with what Richard Stallman refers to as "tivoization," which is the practice of using software available under the terms of a copyleft license but prevents the user/owner from modifying that code through the use of protections. Stallman believes that this is a blatant violation of your freedom. Linus disagrees.

Stallman's argument:

One major danger that GPLv3 will block is tivoization. Tivoization means computers (called “appliances”) contain GPL-covered software that you can't change, because the appliance shuts down if it detects modified software. The usual motive for tivoization is that the software has features the manufacturer thinks lots of people won't like. The manufacturers of these computers take advantage of the freedom that free software provides, but they don't let you do likewise.
