I'm now having an easy time remembering why I switched from Trisquel to
Fedora two years ago: guys with sticks up their bums.
My analysis/proof is that all of the media-related packages he suggested are
already in Fedora's repository or the third-party RPMFusion Free repository
(since those are patent threats and possibly unsafe to include in a major
distro ... but to use the software is still basically ethical). And, while no
FSF, they are serious about software freedom and check carefully to make sure
there is no violation of it within the licensing or the code. I go by simple
common sense: if a piece of software is under the right license and popularly
recognized as Free or "open source", it's quite wise to not doubt it.
Sometimes, there is a freedom issue there, but that's usually not the case.
But who needs courtesy when you can be a saint in the Church of Emacs, right?
