If OpenAI had not went that way that they did I think it's also entirely non-obvious that Claude or Google would have (considering how much impressive things the later did in AI that got never released in any capacity). And, of course, Meta would never done their open source stuff, that's mostly results of their general willingness and resources to experiment and then PR and sticks in the machinery of other players.
As unfortunate as the OpenAI setup/origin story is, it's increasingly trite keep harping on about that (for a couple of years at this point), when the whole thing is so obviously wild and it does not take a lot of good faith to see that it could have easily taken them places they didn't consider in the beginning.
