It's not a cult. I use all three operating systems and I'm highly proficient using linux. My distro of choice is Manjaro and NixOS and I have a lot of experience with debian and ubuntu as well.

Each operating system has benefits and downsides. For user experience linux is definitively the worst. Definitively. The differences are so large that it's almost comical how someone on this planet can't see the difference. If you can't see this then you are the one that is part of a cult.
