I think that shelling out an additional $36 is not too much to ask for in
order to maintain the freedom of your software. I agree it is inconvenient,
and I do not think that anyone will argue against that fact, but we all
believe that maintaining the freedom of our software (and eventually all of
our hardware) is something that we are willing to undergo minor
inconveniences for.
Buying a card from ThinkPenguin will not only allow you to access the
internet wirelessly with your current hardware it will also help to support
trisquel (since they make a donation of all purchases made from the main page
link).
Trisqul and other distributions like it are not for everyone. However, I
believe that promoting software freedom will benefit everyone, so that is why
I continue to use and support trisquel.
