What do you consider these restrictions to be? The way that GPLv3 works against tivoisation is that it requires downstream distributors to provide the information necessary to defeat it, such as private code-signing keys.[1] You think this is an unacceptable requirement? It seems no more onerous to me than the requirement in GPLv2 that the source code must include all necessary scripts to build and deploy the software.<p>--<p>[1] <a href="http:&#x2F;&#x2F;www.gnu.org&#x2F;licenses&#x2F;quick-guide-gplv3.en.html" rel="nofollow">http:&#x2F;&#x2F;www.gnu.org&#x2F;licenses&#x2F;quick-guide-gplv3.en.html</a>
