It actually makes perfect sense to do this if your goal is corporate capture of the market.
From another article :
On one side are leading A.I. companies like Anthropic and OpenAI, which claim that some A.I. models are too dangerous to be developed in the open and must be tightly controlled — by businesses like themselves — for safety.

And more government regulation. These companies constantly cry for universal "guardrails" on AI - a thing that is too nebulous to define, but only these companies have the cash and lawyers to claim they do.
