There seems to have been some sort of recent push at Microsoft on this. A little while back, an update to Office for Mac caused each application to pop a dialog on startup to share "diagnostic data" with Microsoft. The only options were "Full" and "Basic" data sharing. The buttons in the dialog were "Accept" (once you'd clicked an option) and "Learn More". No "Don't Share Data" option. Many users complained in the support forums about this, saying they wanted a way to completely opt out. Worse: if you closed the dialog without selecting any option, you were automatically "opted in" to "Full" data sharing (as you could see if you then went into settings and looked at the privacy tab). This week they rolled out another update. Which sneakily looks like it fixed this; now the dialog has buttons "No" and "Yes", but if you read it the question it's asking is "Can Office send enhanced error reporting?" There still is not a "do not share data" option.
