Not all bandwidth is created equal. Different providers can have widely different levels of performance. Higher-priced bandwidth _can_ also be better bandwidth.

Cloud providers haven't done a great job of explaining this so far, but Google Cloud's Network Service Tiers product is a good attempt at why they charge more for bandwidth, and how you can get it for cheaper: https://cloud.google.com/network-tiers/

That said, cheap (and presumably slower) bandwidth may be the right target for B2, given that it's customers are probably using it for backups and private storage rather than, say, serving a website serving photos to millions of visitors from around the globe.

So comparing AWS or Google transfer costs directly to B2 isn't necessarily a fair comparison, depending on your needs.
