> Anthropic, Open AI & Co. realized at some point that if they can't make money with barely any competition they sure as hell won't if the market is flooded. So here they are slamming the door behind them.

Jokes on them, there won't be new entrants not because the door is shut but because it doesn't actually make money. The whole scheme is propped up by illusions to grift the investors, fewer competition only breaks the illusion. But I guess those folks aren't the types to understand "rising tide lifts all boats", or in this case, rising sewage buoys all rats.
