"I've deleted my diagram, can you restore it for me?"
"No. We don't store your data, we never even see it"
"What a useless service, just get my data back or I want to speak to random escalation person"
99% of users don't care about privacy, architecture, etc. They want it to just work (TM). They want us to be able to undo their deletion, find their data when they forget where they moved it.
So it's users pressuring suppliers in the wrong direction, it's not all one way traffic.
