Doesn't OpenAI gets large part of their funding from Elon?
I mean OpenAI is not a competitor to Tesla.
Now, granted, SpaceX does not file patents because their competition is primarily nation-states [3], but I feel thats a valid concern with regards to that domain.
"We have essentially no patents in SpaceX. Our primary long-term competition is in China," said Musk in the interview. "If we published patents, it would be farcical, because the Chinese would just use them as a recipe book."
