> it's really hard to operate a predictably sustainable (i.e. profitable) business [... with other providers]. Fly just gives us compute at the edge for a predictable price per unit of actual compute resources as opposed to requests, and gives us freedom to serve as much traffic as we can min-max onto those resources, like we could with traditional cloud compute

The praise on the subject of predictability is interesting, given perennial concerns about uncapped vs capped usage charges (with any cloud provider), but esp. in light of past Fly-specific comments that "putting work into features specifically to minimize how much people spend seems like a good way to fail a company".

We ended up shipping a "cap your costs" feature, we just did it with prepaid credits. If you buy prepaid credits instead of adding a credit card to your account, we can't bill you more than you've prepaid. The downside is that you have to prepay $25 to use anything at all.

My comment could have been better. Our business model is predicated on making it cheap to use services and easy to incrementally scale up. We probably won't build features to cap usage of things directly, but it makes total sense to deactivate apps when credits run out.
