Tivoization is a term coined by Richard Stallman and the Free Software Foundation (FSF) to refer to what they believe is a violation of the GNU Public License’s (GPL) spirit, if not it’s actual wording. In response to Tivoization, as well as a few other concerns, the Free Software Foundation released a third version of the GPL in 2007. The wording of the GPLv3 is considerably stricter than that of the GPLv2 and other software licenses, and has been criticized by many in the open source community. The stricter language of the GPLv3 has even been blamed for the current migration from the GPL to less restrictive licenses such as the BSD or Apache licences.

I agree that the GPLv2 is more free than the GPLv3. The GPLv3 was a mistake and the result is people leaving the license.

I release software under v2, and if v4 is yet more restrictive, I think I will change licenses.
