It’s possible to create regulation that enhances competition. For example, we could introduce laws that force companies to follow interoperability standards and oversee the companies to make sure that they’re not sneakily limiting their rivals behind the scenes. This is already a feature of good telecommunications laws, and there’s lots to like about it.
This is something Doctorow has been discussing quite a bit lately, especially in regards to adversarial interoperability. It is also something Stephen Wolfram his touched upon. On the otherside is Kin Lane who argues that interoperability is a myth.
