I wash my hands because I use my hands to manipulate objects, touch my face and prepare food. Perhaps you perform these tasks with your anus?
If I had a sphincter on my hand with shit inside it, which occasionally farted or shit came out, and washing it would never actually make it hygienic because it’s not a hermetic seal and bacteria from the shit inside would always be on it anyway, then yeah I’d just wipe it with paper. And use the other hand
The year of the Linux desktop I’m thinking of was like 2008. That was then it became perfectly usable on the desktop and I haven’t had to switch back since.
I don’t understand why anyone care’s what Linux’s “market share” is. It’s open source, no one makes money when someone installs Linux.
