> I don't think without forcing more customers to loose data (e.g. by requiring them keeping an encryption pin/key) it's possible to perform backups in a (much) better way.
I have full confidence that the industry would be quick to innovate if they were forced to, but that's not in their interest nor the government's interest.
Here's a simple one: Build an open standards-based system where users choose their backup provider and let them decide whether they prefer to have full control over the encryption keys or whether they want them to be managed by a third party. Educate them so that they can at least try to make an informed decision. Warn them about the risks and jurisdictions of built-in providers.
If someone wants to continue using their device as-is? Cool, 2 taps and they're done.
Do they want to store all of their app backups on their NAS? Make it as easy as switching your default browser.
