> BitLocker key backup is about the best way that Microsoft Customer Service or your organisation IT helpdesk can turn around and say "well actually, yes, we can help with this" rather than leaving users to suffer consequences they probably didn't even know about.

This is the best way for Microsoft. They have the keys to data. The best way for other people is education. Just as you lit a match when you're a child and get burned and you learn that fire burns, just like this you can teach people about their data and the consequences of giving it to others. This, of course, does not work because (in this case) Microsoft has a conflict of interest. They want your data. I'm astonished how my company talks about information security when almost everything they have is in the cloud. Microsoft has the emails, Microsoft has the code. Yes they do claim it is secure but the keys are only accessible by the Microsoft OS.

The funny thing is that capitalism was all about property. "I own my {house, computer, car}." I'm really curious how this will evolve in the long term when noone will own anything. A new era of "digital slavery" ?
