While the Hypercard discontinuation in 2004 can be viewed as petty, that was quite late in its life. I think this article neglects many of the developer gifts that came back into the Apple fold via the NeXT merger which Steve Jobs can legitimately take some credit for. Cocoa was a major development which is completely ignored here. Also, the evolution of the World Wide Developer's Conference, and its supporting materials is not covered in the article as well.
While NeXT UI frameworks can be considered great to be made available to an wider audience via OS X and Cocoa, similar ideas were already mainstream on the Windows world via Visual Basic and Delphi, and much widespread in terms of bringing programming to the people.
