If you're on OpenAI, and I'm on Anthropic, can we interoperate? What level are we even trying to interoperate on? The network effect is that, hey, my stuff is working here, your stuff is working over there. So do we move to your set of tools, or my set of tools, or do we mismash between them, as our relationship and power dynamics choose for us.

I'd describe that as platform lock-in rather than the network effect.
