I left a long time ago while they would entertain my classmates of new features I had been using for 4 years. Everyone thought I was embarrassed when the MS rep told me they had to look at legal consequences before adding features that could be patented by others when I asked why they hadn’t added a menu of WiFi access points, yet I sat there wondering how our open source community built so much and took care of each other in collaboration. I understood they had to be careful to not get sued, but they also thrived in that world for competition rather than selling services.
