For a company who's founder talks so negatively about closed formats and DRM, it might be news to you that Linspire Inc themselves implement closed format files and DRM in their own products.
Linspire Inc's flag ship product applies DRM to every peice of software you download with their proprietary CNR software. You are given the opportunity to store your downloaded software in a file format with the extension '.cnr', which is nothing more than an encrypted Debian package file. The result of this is that you are prevented from using the software you download on any other Linux system without Linspire's permission. The CNR installer is required to 'phone home' whenever you want to install any software, just to make sure you have their permission to use it.
What is even more puzzling about this is the majority of the software Linspire delivers is GPL'd. The GPL license entitles you to copy, modify and redistribute your software, so Linspire has no legal protection to prevent you from doing this. But still they are trying to do it anyway.
Fortunately current CNR files are easy to crack, but that might not always be the case.
If you don't think Linspire Inc should have the right to prevent you from using your own (Free) software in any way you wish then email them and tell them so. I have made my own views clear to them. In the meantime here is a program you can use to decrypt these files: cnrtodeb.deb
