Oh, that's simple to answer...
"I have throughout the years found it absolutely absurd that the people refuse to use something that just works and is absolutely free."
No market share. Or tiny market share. What does market share have to do with the running of an OS? Nothing. But I see it quoted all the time like it's a key factor why the quoter finds Linux unacceptable.
My favourite, however, is how one detractor still has to "compile the kernel".
It's not even FUD. It's just ignorance perpetuated by those who need to validate their choice in OS.
Like Linux cares.
