If Microsoft is this hostile and in your face with its paying users, I'm concerned about what its policies are when it comes to its own employees. Are Microsoft employees allowed to use Firefox and Chrome internally on a daily basis or is it permitted only for UI tests? Is there an (un)official internal policy on this? If it is not enforced then I guess they only care about it when money is involved. Not sure how I should feel in that case.
