I came across this snippet. i always assumed OSX was a proprietry system, how does this affect people? Apple closes down OS X Tom Yager, InfoWorld (US online) Thanks to pirates, or rather the fear of them, the Intel edition of Apples OS X is now a proprietary operating system.

Stripped of openness, it no longer possesses the quality that elevated Linux to its status as the second most popular commercial OS.
