The big thing here is trust. They trumpeted OneDrive a year ago for its UNLIMITED storage space. Subscribe to the wonderful world of Office 365 and move your digital life to the cloud, no limits! And now, suddenly, when people actually did do that, they've decided they can't handle it and are going to limit not just new users but ALL users, all of us who bought into the system for exactly what they touted.
Think about this: if Microsoft is willing to get deal with the firestorm of very bad publicity that is sure to come from this, how bad off are they? In how bad of shape is MS where the preferred outcome is every tech news site reporting on this, losing lots of current customers, and possibly poisoning the well of potential customers? Most people do not need Office anymore - Google offers the solid Docs, Apple has iCloud's Pages/etc., and they're FREE if you use their services. Unless you absolutely know you NEED Office, who in their right minds would choose Office 365/OneDrive after this? These are the actions of a company in very deep trouble.
