Well, sure, if we very, very carefully, look only where you want us to look, it looks like you've got a case for something here.
Unfortunately for your argument, OS X is not BSD licensed. OS X is Cocoa. You can't name anything anyone regards as an OS X application that doesn't need Cocoa, and Cocoa is locked up tighter than Fort Meade. If you open an OS X programming guide, take an OS X programming class, attend an OS X developer's conference or seminar, use the interface of any OS X application or tool, it's Cocoa. Cocoa is not BSD licensed. OS X is not BSD-licensed. Apple is not making money off the FreeBSD part of OS X, they're making money off the Cocoa part, and more power to'em.
IBM, on the other hand, sells and supports Linux systems. Oracle sells and supports their own Linux distro.
Google -- Android's little-to-no more Linux than OS X is FreeBSD, so what was your point about people choosing BSD licensed innards?
Oh, yeah: "wrong".
