I appreciate the vitriol, as always, but honestly I can't see what the problem is. Yes automatic updates are nice, but unless I'm mistaken, Apple aren't revoking distribution of extensions outside of the beautiful garden. Compare and contrast with the competition. So unless there's something I'm missing here, I'm inclined to think this is all a bit meh. It'd be nice if extensions could supply their own update mechanism, but in the absence of that, I'll survive. Like the Mac, you can live without Apple's blessing. iOS is the only real straggler now, and as of iOS 9 you can actually develop on your own device without payment. I hope this is a sign of good things ahead, but I'm not holding my breath.
