I'm comparing just storage prices, because I have no idea how Sia works in terms of latency/bandwidth/access. Being distributed, I suppose it will fare worse in most (if not all) these respects compared to Azure/AWS/Google and maybe even glacier.

As for bandwidth cost: I don't believe Sia can be successful and stay that cheap. Why would providers of bandwidth for Sia be able to offer it magnitudes cheaper than the biggest tech companies in the world? Answer: It's offered by a bunch of individuals with no caps on their data plans. If Sia takes off and lots of people start using terabytes of bandwidth, the ISPs will put an end to it.
