OpenAI went downhill fast after Elon left the board of directors due to a "conflict of interest" with Tesla. I don't know if he would have allowed the for-profit restructuring after giving them so much money precisely so that it didn't need profits for AI research. It probably also didn't help that he poached Karpathy from them and put him in charge of Tesla's AI efforts. So it's no surprise that there is a lot of potiential beef here.
So Elon wanted to build an open source non-profit AI but had to resign from openAI, which he had cofounded with that intention, because he wanted to create a closed-source and for-profit AI for Tesla and that brought a conflict of interest. Sounds quite contradictory to me to present this as an argument to construct an image of open-source, non-profit advocate. It reads as "I support open-source etc AI as long as it is others who do it, my intentions are to use AI for profit".
I think you should probably read up on Elon's statements about AI and you would probably realize that, at least from the statements, he doesn't trust AI and has deep concern about it (hence why he was part of OpenAI to keep watch over its progress).
The models used at Tesla are vastly different than the LLM models. There is nuance here.
Tesla was set up as a for-profit company and is such beholden to shareholders, and so using closed-source AI for profit is the path Tesla is going down.
OpenAI was set up as a non-profit company and only beholden to its values, and promised to be open-source.
These two organisations incentives contradict each other, and so it makes sense for Elon Musk to separate himself from one of them. You could argue that Elon Musk should have instead separated himself from Tesla, but that is a big ask for someone to leave their main lifetime project.
I don't think you can put the blame on Elon Musk that OpenAI later became ClosedAI (while not under his watch), some other members of OpenAI have to be responsible.
