Why should I use Trisquel instead of one of the better-known distributions?

'There are literally hundreds of GNU/Linux distributions designed to fill every conceivable niche. Only a handful of them are entirely free software; Trisquel is one such distribution. That's why Trisquel is endorsed by Richard Stallman and the Free Software Foundation.

The popularity of GNU/Linux has skyrocketed in recent years. The major distributions are attracting large numbers of new users, but their distributors are not taking the opportunity to effectively teach these same users to value and protect their freedom. Our software is being advocated on purely utilitarian grounds (such as portability, stability, security, customizability, and lack of cost), so the casual observer is led to believe that "Linux" is just another OS, albeit a useful one. While it may appear to be a reasonable compromise for big-name distros like Ubuntu and Fedora to include some nonfree firmware, drivers, and applications in their mostly-free systems for which no complete free drop-in replacements exist, time and experience demonstrates that this only perpetuates the problem. If we want free software alternatives to emerge, our community must actively reject the non-free counterparts.

Trisquel is different. We naturally want to bring you an operating system that is tight, beautiful, and robust. We want your software to be feature-rich and work exactly as you expect it to. But we'll never compromise your freedom, either.'

uh-oh. this could be a problem...

Does Trisquel include proprietary software?
...
Note in particular that no binary-only firmware for wireless cards or proprietary drivers for AMD/ATI and NVIDIA graphics cards are included.
