To me it is all just really good fun. I'm not sure why others would leave, my guess is there are a number of reasons. It is hard to put anything creative out there publicly that has any deeper meaning for you. Plus some people have some long standing issues with what is a 'right' way to make wealth. Anything that doesn't fit the ideal of going to 'work' from 9 to 5 seems to be looked at with some suspicion.
