Its up to you where you draw the line. We're not in the business of trying to
control your computing (that's what non-free software does), contrary to what
some critics tend to say.
But if you choose to use non-free software, we won't help you with that.
Speaking of which, I have a laptop whose wifi card requires non-free
firmware. Windows works with it, of course, but I'd rather not use Windows.
For the long term I'll buy a freedom respecting wifi card (preferably PCMCIA,
if there are any that are freedom-compatible) but for now I'm seriously
considering using the proprietary firmware as a short-term solution. I figure
it's either that or Windows, so I'd best choose the lesser evil.
