I’m not against this, by that point there will be another hosting provider with even cooler features for small companies to make their next startup in.

Fly.io are doing great I think and that they might one day charge more I’m not that upset by it at all. If fly.io can make money at a higher price that means they are adding more value.

I hasten to add you appear to be hanging out on a forum focused on VC funded startups.
