My friends send me e-mails and messages, which I read with open source software, with links to news articles that I read with open source software. I message with open-source apps using open standards.

I manage (and share with my peers!) the books for an organization with GNUCash.

I collaborate on and write papers with LaTeX, write my code in languages with open standards, use primarily open source compilers, and run my code on Linux cluster which use open-standard parallel communication APIs and open-source implementations.

I do not play video games.

My office printer is plug and play with Linux/CUPS.

All done on my trusty custom linux distro (Exherbo) for years. Oh, and I haven't reinstalled since 2010 but I am running the most recent open-source GNU/Linux software.

Maybe my life and my needs don't match others', but then again maybe erikbye's don't either. Anyway, that is why I do not care about more people using Linux. If anything, more Linux users have made the internet a less useful resource for helpful Linux knowledge.

Why should I care?

P.S. my phone is another story, but I expect different things in that space.
