Intellectual property. My employer has an agreement that our code will never end up as part of Claude's training data. At this point there are also now custom Claude integrations etc.
I'm sure they could also negotiate a similar deal with OpenAI but in my outsider experience it seems that negotiations around these kind of corporate contracts takes forever and when the selling point is "they're broadly pretty similar" I suspect the motivation isn't there.

“Our competitive advantage is that we believe them,” I’ve read—wonder if that’s still a [prevailing] sentiment.
(Edit - context was probably using SotA models instead of being limited to local open source only)

Bit of a tangent but it is funny to me that so many companies talk about how some large percentage (sometimes 100%) of their new code is LLM-written and they still bother to worry about their code being used for training.
If an LLM is writing all your new code then your existing code certainly wasn't some unique special secret, and your new code came from the LLM to begin with.
