"proprietary software is never a solution"
Reflecting on this some more as I went for some groceries. There's I
was paying for things from a computer controlled refrigerator
(non-free software) using a debit card in a reader (non-free
software) through a POS terminal (non-free software) using my bank
account (non-free software) in an air conditioned shop (non-free
software).
So, until the free software movement is further down the line,
'never' is mere cognitive dissonance.
More like - not on my devices that have GNU/Linux built for them
(Replicant devices use non-free code in the modem/DSP side of the
hardware) unless I have absolutely no other choice and am absolutely
certain I'm not indulging in what Satre called 'bad faith' when I
make that choice. And obviously I buy free software capable devices
when there is a choice.
Or to put it more simply - I always seek to maximise my software
freedom. Which, I think, is what will be your reality too.
