You dont seriously believe if you check a box that says "keep no logs!" they will.. not keep any logs?
Especially the idea that somehow Fly.io wouldn't keep track of which IP is signing up for service - kind of important, constantly, for CSAM investigations and the like.
Of course not, but that's a separate problem that I didn't treat. It was about the ability to make that choice, I don't think that that my choice should be respected is a controversial statement worth debating.
