This isn't really a rant about these people but from this story that I just read online that should put these people to rest.
So basically the author of the article describes how his 88 year old Father-in-law is mostly confined to his house because of old age - a very boring environment. So he sent his father-in-law an Ubuntu CD. And then it all gets better - so read the article!
I thought it was really cool - especially because I've been seeing a lot of people complaining about Ubuntu like "why doesn't it just work" and other things when this 88 year old man got it to work seemingly perfectly.
