Bring back the 1990s.
It really doesn't matter if MS can see German school work. But perhaps all this weird data nationalism may push us back to having software on local media, storing files on local media, rather than the cloud. Which would be much better than subscriptions for online services that can have features removed at the drop of a hat, charging you every month, and storage of your files on someone else's server, that can be accessed and scanned by third parties such as your own government, via back doors.
Bring back the 1990s. Just not those AOL CDs.
