Absolutely. And this is a mere request from them, not something they can actually tell their customers. Apple is the sole judge on whether you shall receive a refund. The actual maker is not involved in that process.

It's still kinda gross, IMO. Twitterific should be pro-actively refunding customers for the unused portion of their subscriptions, without users having to request one from Apple.

Twitterific made a bet that the Twitter API would remain available to them. They should be the ones assuming the risk and taking on the consequences of losing that bet. Not their customers.

It's my understanding that Apple doesn't offer this feature.

This is correct, they couldn't do it if they wanted to.

Sometimes Apple Dev Relations will help out and mass refund without making all the users request a refund, but they don't always (even when the developer asks).
