The problem is that OpenAI has cornered the market. Maybe they haven't crossed the legal line or more to the point no one in this corrupt and incompetent administration is going to prosecute them, but buying up 40% of a market which hasn't got any additional capacity is cornering by any measure.
So yes, this is not a normal market. Your claim of a functioning market is the same as saying my laptop, having lit on fire, is a functioning computer after having 10,000 volts applied across it.
