This is a feature that has been among the most loved aspects of its main competitor for more than a decade.
Somehow, Microsoft managed to make the same feature sound and feel and be creepy.
This has the effect that (to a first approximation) everyone knows someone with a horrific OneDrive data loss story, no-one particularly trusts OneDrive with anything actually important, and so no-one wants to be forced to use it for everything.
However, OneDrive's promise is "save your files and photos to OneDrive and access them from any device, anywhere". Accordingly, the model OneDrive actually exposes to the user is directory trees of arbitrary files containing what, for OneDrive's purposes, are opaque blobs. This leads to all the behaviours you'd expect from a distributed system using such a model, and therefore the trust issues the public has with MS distributed systems.
Regaining someone's trust in a vendor after a bad experience, even for a different product, is very hard.
