Me: "Hello. Could you tell me what Microsoft is doing at this Linux conference? I honestly want to know that."
Him: "We are here to show how our products can work well together with Linux related products."
Me: "Why would I as a Linux user use Windows or any other product from you? We all know that you spy on me - at least indirectly."
Him: "Oh no. You are misinformed. We have a lot of business customers with very sensitive data. Can you imagine what would happen to us if they found out that we spy on them? Business users are very sensitive in that area. We were screwed. And we do not spy on regular users as well. You may also know that this would be totally illegal according to German law."
Me: "So you are saying that you do not spy on businesses or other kind of users of your products?"
Him: "Yes! We were screwed otherwise!" *giggle*
He had a smile on his face for the whole discussion. Maybe because he had this discussion with those paranoid Linux users for the last couple of days of the conference. Paranoid!Microsoft is so screwed guys.
Edit: I was not rude to this guy. We had a beer together later that day. I am sure he did not know anything about PRISM and was just doing his job.
