For *personal* cloud storage, I think that pay-for-quota should be the new status quo de-facto. I think bits and volts are comparable enough to have matching pricing model. Huge number of TB's or unlimited quota do not make much sense from sustainability point of view.
With similar pricing model to electricity, e.g. optional carbon compensation would be trivial to implement.
I realized that I've paid for few years 2 TB Dropbox with 100GB quota at max so it makes at least for me a lot of sense to move this of cloud. There's a few pretty decent S3-compatible options available for personal use, which is also a factor more robust than using Dropbox with its awesome apps (of which I've ever used none) :-)
Paying less and having full control of the storage works for me.
