In my opinion, the current mores of the company are pretty irrelevant; power dynamics are what matter.

Tides change. Whether or not Microsoft is benevolent today, they may not be in 5+ years.

Any company large enough to screw me over without feeling the loss of my (and people like me's) business in their pocketbook, is not a company I want in a position of power over me. Adapted to this conversation: we should not tolerate "extend" from any company that could successfully pull off "extinguish".
