In my case it was because Ubuntu broke on me for whatever reason (and the threat of snap packages looming).
I did not feel like putting anymore effort into getting the computer back to working so I just switched to something not Ubuntuoid at semi random to anything that promised an easy installation.
A year later and it’s still working. I’ll notify you when it breaks so you can tell me “I told you so”.
Dabbled in it since 2006. About 2012 i had problems with my network card on windows, flipped out and just installed Linux on my main home computer and have not used windows at home since.
Started with Ubuntu and it’s flavors, recently had problems with snap packages, flipped out and installed the first non Ubuntuoid distro that promised an easy install so I could get back to whatever I was doing at the time. I currently have Manjaro at home.
