Microsoft did not respond to a request for comment on the report and its recommendations.
Microsoft are dragging their heals on this but all the work is done already, there is a special version of Office 365 for Germany with the telemetry disabled which talks to servers located in Germany.
Maybe they decided not to comment because they can't think of a good reason why this shouldn't be offered to the Netherlands apart from them wanting to hoard it.
