I know I've shown this before but I'll show it again.
In the country I live in there was discussion of outlawing Windows 10 because - as of August 2015 - it broke too many Swiss data protection laws to be legal.
From the news link below:
"Depending on the result of the investigations, Microsoft will be recommend to make changes to Windows 10. Conceivable changes could be to expressly give users the opportunity to consent to certain data transmissions to Microsoft (so-called "opt-in") and the users must be better informed. If Microsoft rejects any recommendations or doesn't comply, the commissioner could refer the matter to the Federal Administrative Court. The last resort would be the Federal Court."
Doesn't this raise any red flags with you at all? I'm amazed to see some people here using arguments such as "well, I trust Microsoft more than other companies".
...What? I refer you to a previous post mentioning Microsoft previously cooperating with the NSA and I refer you to my signature where you will find a link to Microsoft's official privacy statement, which basically says "we can collect any data we want and we can do anything we want with it".
