Apple's product roadmap is littered with the trail of dead 3rd-party programs that did a better job. f.lux can't be unaware of this. Who uses Growl anymore? Now that Finder has tabs, who bothers with Path Finder? Rogue Amoeba went cross-platform and built out a bunch of different apps as soon as Apple finally got their shit together with airport streaming and Airfoil was no longer relevant. They're a predatory organization that knows they can crush you the minute you come up with something interesting. They also don't give a fuck about you. When Path Finder was providing vastly superior handling of cross-platform file operations, Apple responded by forking the crucial parts of Apache closed-source so that the only way to continue to function was through kludging. This is the principal reason Back to My Mac works over Airport hardware and not at all over anyone else's routers: it's an ad-hoc blend of iPv6, SMB, Apache and haxies that changes whenever Apple feels like it because fuck you, they're apple. I think there's a reason all the clever Mac developers are going cross-platform. The leading edge is realizing Apple under Cook looks a lot more like Apple under Sculley than it does Apple under Jobs. I bought a PC for the first time in 15 years.
