This seems an interesting point and one I share. Yet it seems equally unethical to enable the corporate extractavism that we now see. It's time the "users should have the freedom to do what they want with software" be updated to something like 'users and makers should be free of coercion and exploitation by software.' What, after all, are the grounds for such freedoms? Are they issues of property? Or are they ones of the dignity of the persons involved? It doesn't seem controversial that we tend to find it problematic if another uses us as means to their ends without our consent. In personal actions, many act as if they believe this. Yet corporations consistently do not act with those values. You're right: we should strive toward a system not in which it's viable to create businesses out of FOSS but in which both users and developers are not exploited or used unwillingly.
