They now say this is related to the diagnostic level set to full. This is clearly not true. I have disabled ALL privacy related settings, set activity X to off and have the level set to basic since install. Microsoft still displays search queries and apps I used on the activity dashboard. Clearly someone "messed up". (Collect now, apologize later)
