I agree with your point in principle, and yet I installed Ubuntu on my work laptop this January after using Windows professionally for my entire (5 year) career. I've found myself moving in the opposite direction from the person in the root comment, because I find that it's getting harder and harder to find tolerable proprietary software.

I mean this in the nicest possible way: 5 years is likely not long enough for the “just work, stupid” desire to really, really, really set in. Nor is a couple of months enough time for the potential rough edges of desktop Linux to set in.
As a power user, Linux is just so much nicer. I constantly get frustrated, especially with macOS, about stuff that I can’t easily. In Linux my stuff works and if it doesn’t it can be made to work (usually). In Windows/Mac it’ll often take considerable effort to make the system work the way I want, or it’s just not possible.
