As a contractor I have been a victim of _all_ the examples in that website (yes, even Interix. A company I used to work for immediately tried porting their software to Interix the moment it was released for free (I think XP?), and I still have nightmares to this day. God bless that guy who used to have a website with more recent GNU utilities for Interix). They only really succeeded in some of them (e.g. MSN, browser, email) but they definitely tried. Sometimes it was legal reasons that stopped them (e.g. Java) and not just their incompetence.
