Your first sentence claiming that apps must be in the Mac app store in order to use low latency HLS video streaming doesn't appear to be right. The help.apple.com support page you link to says that the API is limited to developers who have Apple Developer Program membership, but that page doesn't indicate that the apps must be distributed via the app store. That's a big difference. Is that limitation documented somewhere else?
Isn't this almost the same as the Windows/IE bundling antitrust case? Actually it's potentially worse.<p>Basically they have disabled a feature that already exists on the OS, and only let you take advantage of it unless you use their bundled system (app store).
Just say "no" to Apple --- as most people already do.<p>They have their captives, fans and "subscribers" but for most, their approach is a non-starter and has been for at least the last decade.
Screw Linkedin.<p>And if you don't see value in having a walled garden, then go back to Windows. Most people need computers to work, not to be playthings for themselves or for unscrupulous developers. If Macs become appliances, then good.
