This is what I'm thinking too. Narwhal is sticking around but once Narwhal 2 comes out it'll be $5-7 per month and more for a user who makes a lot of API calls. If I'm remembering correctly Christian figured it would be close to $10 per month to support Apollo's heavy users without going in the red. That's crazy money to pay for access to Reddit.
Good explanations in your article! In case you may not already know there's a kbin app (later to work with lemmy as well) called Artemis in the works as well.
You’re all good! I’m also an Ultra + Pro user and there’s no refund needed. Apple treats that kind of transaction as a one time payment. It’s only those who subscribe for a set amount of time (month or year) that are offered refunds.
