They're going to limit you if you spin up a bunch of cheap instances to use up their bandwidth, but if you pay $300/mo for their 3 Gbps connection you can saturate that and they don't care.
You can’t compare it like that as the calculation is different. If someone eats a small part of their meal or the whole portion doesn’t change the outcome for the restaurant. They can’t sell the rest to someone else, if someone doesn’t use bandwidth someone else is going to use it.
