I cancelled my subscription since I received a notification that my browser is not supported.
Perhaps I should have mentioned my issues with DRM as well, but this may have gone too far. One message is clear, too many messages are noise.
Either Linux or GNU/Linux is OK to me. It's the practice that makes the difference. While I mostly use Debian, which defines itself as GNU/Linux and I appreciate every aspect of it, I recognise that Arch Linux (which drops the GNU) has a much healthier approach to free software than Red Hat (recently at least), which defines itself as GNU/Linux but adds clauses to RHEL which are against the spirit of free software.
I prefer using GNU/Linux because, as a statement, respects things that are important to me. Of course, I am totally cool with other people using any term they feel more comfortable with.
