People won't start using "free and open software/hardware/web services exclusively", because none of that matters for the end users. I do like and use open source for infrastructure, this is where it shines. But as Joe User I prefer highly polished (and paid) apps to "free" software which is powered by advertising. I am sick of this "advertising will pay for everything" world with ever increasing noise and subpar quality. How about paying some real money for some real work?
