This attitude will just lead to pretty much every product being closed and proprietary. Which sucks for me, because I like to be able to read the source and run modified versions of tools I use, and have no interest in creating competitive derivations of them. So I think it's a shame that people who try to make software like that get pilloried for being neither proprietary enough (which is apparently fine...) nor open enough.
