I think what most of the people here are missing is how big, how paranoid, and how influential the "AI alignment" movement is. From everything I've heard and seen, the actual researchers at OpenAI are trying to take seriously the risk that a super-intelligent AI might destroy the human race. To
you it looks like they're being overly careful and paranoid, perhaps as an excuse to set up a monopoly silo to extract money. But a
lot of the people they work closely with -- people deep in the "AI alignment" community -- are telling them that they're being wantonly reckless, helping set the human race on a path for certain doom.
From that perspective, the opening of ChatGPT has actually been very effective at raising awareness. All the way back in GPT-1 they were trying to raise warnings, but those warnings didn't get much popular traction. Now that so many people have used ChatGPT (or Bing), I'm now having conversations about what computers "know" and "want" with my aunt on Facebook.
Furthermore, if OpenAI has the best tools and sells them to everyone at a reasonable price, then there's a reduced incentive for other people to make their own tools. Whereas, if they were to close off access to the API, and only offer it to large corporations, there would be much more incentive for people to experiment with AI on their own -- and in doing so, possibly create an "un-aligned" super-intelligent AI which would destroy the human race.
So my prediction is that given their motivations, they will 1) stop releasing details of their models to anyone other than research organizations they consider careful enough 2) continue to sell reasonably-priced access to the APIs, to reduce the risk that other people will step up to fill the demand who are less careful.
