Ignoring the media kneejerk reaction to this story, firstly the EULA that prompted it isactually the Windows Services Agreement, not the WIndows 10 EULA. Secondly this isn't new; Xbox Live and Skype have had a pretty similar version for years (as 'Terms of Use'), this is just the consolidated version. And if you've already got a Microsoft Account, then you've already agreed those terms. You can see for yourself here (something perhaps the media ought to have done), which includes an explicit list of the services it covers.
