It was a weird point to make in the post given that exe.dev charges $0.07/GB for transfer. That's arguably worse than the major clouds, who charge about the same for egress but give you free ingress.
I need to fix our transfer pricing. (In fact I'm going to go look at it now.) I set that number when we launched in December, and we were still considering building on top of AWS, so we put a conservative limit based on what wouldn't break the bank on AWS. Now that we are doing our own thing, we can be far more reasonable.
Oh, that’s too kind. More like 100x to 1000x. Raw bandwidth is cheap.
