On this day suddenly folks come out of the woodwork advocating for half baked measures to achieve what Stallman portrayed but they still hardly recognize this was EXACTLY his concern when he started the Free Software movement.
Stallman's statements about how the person controlling nonfree software "is your master" are important, but they don't go far enough. The problem is not just the controlling of abstract intellectual property like intellectual property rights to particular software. The problem includes the actual control of how services are provided. When the provision of important services --- be they auth, email, banking, groceries, whatever --- is concentrated in a few hands, those hands become masters of many, regardless of the software licenses involved.
