the GPL establishes requirements that prevents you from gaining power over others through the software. but again, that's about power, not freedom.

you can still place the software at your service to whatever ends you wish, inasmuchas those wishes are within your own freedom, rather than about overpowering others

I acknowledge that some wish to conflate freedom and power, and to gain power over others. the GPL is not conducive of this kind of abusive relationship.
