Such a system would be amazing. It would really force companies whose products are UIs on top of S3 to compete hard because adversarial interoperability would be an ever present threat from your competitors.

It really is such a shame that all the projects that tried/are trying to create data sovereignty for users became weird crypto.

I agree with both halves of your comment, but I realized I can't identify the connection between S3 oauth and data sovereignty. Could you elaborate?

So the idea would be that you have an account with AWS (or realistically a more consumer friendly service that's Amazon branded) where all your data lives. Then when you use say Dropbox you can pick "Use my own storage" and grant Dropbox via OAuth the ability to write to /dropbox in your bucket and all your files would live there instead of Dropbox's servers. Lots of the data sovereignty solutions also include a database like interface you can grant apps the ability to use but I can't imagine that catching on initially.

Apple actually already does this with iCloud storage but hides it really well so it feels seamless.

Isn't this essentially how the Dropbox API already works (for apps that support using it)? I've used many apps over the years that offer this option alongside some alternatives.
