theodp writes "'Apple,' writes Dave Winer in The Un-Internet, 'is providing a bad example for younger, smaller companies like Twitter and Tumblr, who apparently want to control the 'user experience' of their platforms in much the same way as Apple does. They feel they have a better sense of quality than the randomness of a free market. So they've installed similar controls.' Still, Winer's seen this movie before and notes, 'Eventually we overcome their barriers, and another layer comes on. And the upstarts become the installed-base, and they make the same mistakes all over again. It's the Internet vs the Un-Internet. And the Internet, it seems, always prevails.' Thinking along the same lines, Cory Doctorow warns the stakes are only going to get higher, and issues a call-to-arms for The Coming War on General Purpose Computation."
