I think the line should be practical. Personally, I switched to running Linux full-time about 15 years ago. Never looked back. But I still used nVidia drivers even though open source would have been preferable. Using anything else was hell, though, and investing the time I didn't think was worth it - there's a life to be lived outside of computers. These days, Intel GPUs and older Radeons have good open source support, so I use those.

I still use Skype, because that's what my (overseas) friends use. If you start going off on too much of a philosophical crusade trying to convince people to use open source tool X, more than likely I suspect most people will start thinking you've gone a little off the deep end.

For personal use, I try very hard to only use open source software, even if I know there are closed source alternatives that might be more polished / productive. (That trade-off is becoming less and less common; I find the quality of tools has improved drastically over the years.) Also, I try to contribute patches - or at least bug reports - whenever I can.

My point is, you gotta pick and choose your battles. Running an open source OS? Highly achievable. Changing the culture of the internet? Not likely.

--- I should add, wherever you end up drawing the line, good on you for taking the jump!
