"Sworn off" ? Do you mean "sworn at"? I've sworn at Microsoft many times. I still have to use Windows and Office at work. I use RHEL for software developmen

"Sworn off" ? Do you mean "sworn at"? I've sworn at Microsoft many times. I still have to use Windows and Office at work. I use RHEL for software development work, but the Windows 10 desktop environment is better than Gnome 3 desktop environment. We don't always get to choose what we use, so it can be hard to swear off anything unless it is entirely personal use
