theodp (442580) writes "With its forthcoming Lion Mac OS and new Apple-curated Mac Apps Store, Apple will be locking down top tier applications on the Mac similar to how apps are locked down on the iPad and iPhone. Only by submitting their apps to Apple's store and giving up 30% of their receipts will developers get to take advantage of two new OS features — the first is Apple's new 'Launchpad,' a tool for easily opening application; the second is the ability to update apps to new versions with one click. It will be a lot easier to use apps bought from the Mac App Store than ones downloaded in the wild. It didn't have to be that way, says Valleywag's Ryan Tate: 'Apple could have enabled its Launchpad and auto-update features for all applications, sold through the Apple Store or not. For example, an open system for updating applications has been in use for years on Ubuntu, a Linux based operating system. Ubuntu's 'Apt' (Advanced Packaging Tool) lets users install, update and remove software of their choosing with a single command. There's a central list of apps curated by Ubuntu's maintainers, but users are free to add and install from other lists, as well. But Apple seems to have made a very clear choice not to take the open route.' Longtime Apple developer Dave Winer was also concerned, tweeting 'Is this the end of the Mac as an open platform?' during Apple's presentation. The news also prompted developer Anil Dash to call for an open alternative to the Mac App Store."
