They do it by targeting consumers without technical experience or need for backwards compatibility to preserve the value of that experience. That's obviously a big market. But whenever someone else tries to copy that model it is a loss for all of the existing work and experience that built on earlier versions and needs compatibility to continue. For what it's worth, I haven't found it to be that much harder to find Mac ported versions of complex open source software (e.g. vlc) than for RHEL/Centos - they all break things pretty badly on major upgrades, and there is usually just one OSX version needed versus a bazillion linux flavors with arbitrary differences). -- Les Mikesell lesmikesell at gmail.com
