Still way too high. Also, the actual figure I saw from the Apollo dev (different from the Relay dev's numbers) was 345 API calls per day per user, which changes your math significantly.
The other issue was that 30 days notice is not even close to enough time to pivot in terms of business model. He mentioned he has significant operating costs already, due to paying for caching servers as well as part-time help. Not only does he already have to refund users who paid for year-long subscriptions, but he'd also have to turn around and ask them for almost double the money for the same service.
The fact that he's shuttering his business entirely (thus foregoing all potential profit) rather than "printing money" as you put it, makes me think he has a good reason to think his financial situation is a lot more untenable than your rough analysis would indicate.
