I just recently installed Microsoft Office 2011 on my 27" iMac (2009 i5), and it absolutely shocked me that the default "Send User Data to Microsoft" option was `OPT-OUT`, requiring the user to manually click a radio-button to `OPT-IN` to usage data collection.
This was in recent living memory. From Microsoft.
