Why not? What part of Fly.io is competing with any HashiCorp products?

I mean, they allow you to create a manifest that then auto provisions some infrastructure, so... Shrug

I'm being half-serious. Of course the point is that "competing" is deliberately very poorly defined, and it's entirely on the whim of hashicorp to decide whether or not you're competing and then impose a lot of legal costs on you.

It's a racket.
