One of the big problems from a developer perspective about the Mac App Store is that it doesn’t allow developers to sell paid upgrades to their apps. Similarly to the iOS App Store, if a developer wants to make money off of a particularly juicy update, they need to sell it as an entirely new app or else… tough beans. Especially on the Mac, this is an issue, since many developers monetize on-going development of apps by selling paid upgrades. But if you sell in the Mac App Store, it’s just not an option.
Last week, the Omni Group released a little app called OmniKeyMaster. The ingenious little app essentially allowed people who had purchased versions of Omni’s apps on the Mac App Store to essentially “break out” their apps from the MAS into standalone licenses which were eligible for paid app upgrades. Guess who didn’t like that idea?
