OpenAi's transition from non-profit organization to for-profit company is almost complete.

After the last funding round, OpenAI is nearing a $150 billion, and Sam Altman aims to keep a 7 percent equity stake into the company, meaning his net worth will shot up by $10.5 billion.

Together with transition, or perhaps because of it, several key figures stepped down, including OpenAi's CTO Mira Murati (pictured below).

Elon Musk, who co-founded and funded OpenAI, has often criticised Sam Altman, accusing OpenAI of going against its founding principle.

Namely, Musk believes OpenAI's transition from non-profit to for-profit illegal.

He once used an interesting metaphor for it.

"It does seem weird that something can be non-profit, open-source and somehow transform itself into a for-profit, closed-source," Musk said.

"Let's say you funded an organisation to save the Amazon Rainforest and instead they became a lumber company, chopped off the forest and sold it for money, is that legal?"

Musk left OpenAI a while back, and founded his own AI company, X.Ai.
