Their problem right now isn't adding more customers - they seem to have more than they can handle!
If I were them I'd focus as many resources as possible on making the stack rock-solid, and away from acquiring more customers or adding more capabilities.
In fact I'd try to down-scope some features if at all possible, like the example they give of disabling app deploys while they're doing platform updates.
We use fly.io at a small scale and it's worked really well for us, but the money is in customers at a larger scale who must have 100% reliability.
