I'd also consider the need for a possible third dimensions, which would be the quality/usability. I do not subscribe to the "pay with sweat". If that would be the case, one could arguably say that you pay for the proprietary alternatives with anti-patterns, forced reboots and update interruptions, and a lot of effort to try and make the operating system not work against you or spy on you. Of course subjective, but I'd for example place Linux in free, open, and high quality. Similar with blender. Windows would be paid/proprietary but not that good. Etc
