Thanks. I didn't know the history on channel ten. Interesting!
It's true that Mac and Windows are very popular, and the points you make follow from that.
But for out-of-the-box thinking and doing, Linux is often nice, and individuals (not companies) sometimes respond to that. For example, Olivier Gillet of Mutable Instruments has Linux-based development kits on github to allow folks to customize the firmware on their modules. (He made it virtualized, so that people using Windows and Mac can run the Linux virtual machine he configured.)

I'm doing this in my free time the way I want to, and I don't want to use Mac or Windows, so it's part of the challenge figuring out how I can best accomplish my goals without those systems. I don't feel constrained at all today, in contrast to year 2000, when it was way harder to use Linux for digital audio in a full-experience kind of way.
