In my latest podcast (MP3), I read my essay SAMBA versus SMB: Adversarial Interoperability is Judo for Network Effects, published last week on EFF's Deeplinks; it's a furhter exploration of the idea of "adversarial interoperability" and the role it has played in fighting monopolies and preserving competition, and how we could use it to restore competition today. In tech, "network effects" can be a powerful force to maintain market dominance: if everyone is using Facebook, then your Facebook replacement doesn't just have to be better than Facebook, it has to be so much better than Facebook that it's worth using, even though all the people you want to talk to are still on Facebook.
