When computers have issues it is my fault, I made a mistake. There is no human element: I have complete control, in contrast to many painful events in my life. The computer is not being malicious or judgemental, the computer cannot traumatize me. It just takes an instruction and executes it.
I think, on an emotional level, that is why I cling so much to libre software. My computer is the one thing I have control over. Don't take that from me.
