Of course, this all depends on the investment details specified in a contract and the relevant law, both of which I am not familiar with.
Seems like "more or less" is doing a lot of work in this statement.
I suppose this is what the legal system is for, to settle the dispute within the "more or less" grey area. I would wager this will get settled out of court. But if it makes it all the way to judgement then I will be interested to see if the court sees OpenAI's recent behavior as "more" or "less" in line with the agreements around its founding and initial funding.
