Because people want to protect their businesses?
I don't even think it makes sense to use the closed, API-access models for core business functions. Seems like an existential risk to be handing over that kind of information to a third party in the age of AI.
But handing it over to the guy who is simultaneously running for-profit companies that contract with the government and seizing control of the Treasury? To a guy who has a long history of SEC issues, and who was caught cheating at a video game just to convince everyone he's a genius? That just seems incredibly short-sighted.
? there's tons of businesses and startups building on closed models already
the risk is mitigated by competition in the space and commoditization of LLMs over time. This isn't like building an app solely on Facebook platform or something. It's very easy to swap models. There's platforms that let you use multiple models with the same interface, etc.
