It seems to me that Microsoft needs to get better writers for their EULAs since they can be interpreted so freely. For example, I've had a discussion with someone that believed their EULA language meant that if you used Gmail for your email that Microsoft has access to that information. To me, that wasn't the case since Microsoft's language specified that if you used OneDrive and other Microsoft services they were indexing such information. But if you're using Gmail or a third-party client/service then that information isn't under the EULA. But the other person still construed that Microsoft was spying on their emails which seemed odd to me since Google already uses your emails through Gmail to market to you so why complain now?
Either way, I hope the discussion forces Microsoft to make some clarifications on what is being documented and what isn't.
