Of course this breaks down once you have a competitor like Anthropic, serving similarly-priced Plan A and B for their equivalently powerful models; adding a more expensive decoy plan C doesn't help OpenAI when their plan B pricing is primarily compared against Anthropic's plan B.
Leadership at this crop of tech companies is more like followership. Whether it's 'no politics', or sudden layoffs, or 'founder mode', or 'work from home'... one CEO has an idea and three dozen other CEOs unthinkingly adopt it.
Several comments in this thread have used Anthropic's lower pricing as a criticism, but it's probably moot: a month from now Anthropic will release its own $200 model.
As Nvidia's CEO likes to say, the price is set by the second best.
From an API standpoint, it seems like enterprises are currently split between anthropic and ChatGPT and most are willing to use substitutes. For the consumer, ChatGPT is the clear favorite (better branding, better iPhone app)
