By demand, I think he means more orders. If one million people from every
country in the world would email suppliers like Chris saying, "please we want
free software laptops", that would not make anyone like HP, Lenovo, or
whomever produce them.
But if everyone starts buying stuff from Chris, or from any other supplier
who is selling free software compatible hardware, profits from manufacturing
closed hardware will drop. Thus the big companies will say "fuck Microsoft
and the gang, we can't make money with those greedy idiots. We have to go
with the times and produce stuff that operates with free drivers and has no
DRM, unless we want to drop out of business."
That's the kind of thing we need to reach. I know for sure my next piece of
hardware will come either from Chris or from somewhere else where my freedom
is respected. It's just I don't need anything right now and have to save up
for more important things.
