Linux /ˈlɪn.əks/ Noun 1. A piece or collection of software incorperating the Linux kernel; Android. 2. A piece or collection of software resembling the common Linux distribution; GNU/Linux.
Not to mention a wide variety of devices and platforms that make use of the Linux kernel but are not remotely what you might expect from a free software kernel -- everything from Android to smart televisions to cameras to light bulbs.
Ironically, proportionately speaking there's probably more locked down Linux devices than there are locked down Windows devices.
I bought a keyboard for my pinephone and use i3wm on arch. I still can't get right click to work on the touch screen, but I mainly use ranger and nvim, etc., so it's not a huge deal. Basically, I have a tiny laptop that I can use to do work on the toilet.
