If you're Microsoft
If you’re Microsoft and you want users to use OneDrive, you have two choices:
Option 1: Offer it to people. When they say no, just start uploading their things to it anyway, dark-pattern away the ability to opt-out, and start deleting their local files. There, now they’re using OneDrive.
Option 2: Make it be something they want. Actually, rephrase the entire question, don’t make it about OneDrive at all, just make it all about making things that people want and giving it to them.
The choice is up to you?
