I don't find that pricing objectionable on its own, but I'm wary of shopping with a vendor that advertises price as their main selling point, but buries such a potentially costly pricing detail.
I use it for live data, but I put it behind BunnyCDN. I serve a few terabytes per month using that setup, no problem.
Most real world uses that I’m aware of follow the 80/20 rule, meaning you’ll store much more than you serve. And your hot paths are quickly cached by a CDN.
