The reason for the ban were in the MS conditions:
We may automatically check your version of the software and download software updates or configuration changes, including those that prevent you from accessing the Services, playing counterfeit games, or using unauthorized hardware peripheral devices.
and some fears
“What’s particularly nasty is that apparently it sends the results of local(!!) searches to a well known anti piracy company directly so as soon as you have one known p2p or scene release on your local disk … BAM!”
Now this Windows 10 paranoia is completely uncalled for according to Microsoft.
This is the reality according to MS
1Windows 10 collects information so the product will work better for you.
2You are in control with the ability to determine what information is collected.
The Microsoft executive continues:
We aspire to deliver a delightful and personalized Windows experience to you, which benefits from knowing some things about you to customize your experience, such as knowing whether you are a Seattle Seahawks fan or Real Madrid fan, in order to give you updates on game scores or recommend apps you might enjoy– or remembering the common words you type in text messaging conversations to provide you convenient text completion suggestions. You are in control of the information we collect for these purposes and can update your settings at any time. Note that with new features like Cortana which require more personal information to deliver the full experience, you are asked if you want to turn them on and are given additional privacy customization options.
Eh well .. I get the experience part but is this not breaching privacy? Is this not targeting adds?
Microsoft also strictly stated that "unlike some other platforms", it does not collect your personal data from files, emails or any other communication method, which could be used for targeted advertising if in the wrong hands.
..So it "does not"..but could it?
It looks very much as an attempt to position Microsoft as "the right hands" but the data they collect are still subject to your - the market's - trust.
In general it is hard to tell where the line goes between what Microsoft collects - and what they do with the collected data.
Microsoft argues that they treat your data fairly - but isn't the interesting question what they collect, regardless of their fair nature ?
Microsoft wants to build trust by addressing the issue.
They have a site where you can ask your privacy questions and will answer within 48 hour's
I just asked the following question
Is there an overview over exactly what Windows 10 collects with the default settings to servers like ssw.live.com and others?
I am genuinely interested in the answer
