It is even worse if you recommend that others run the nonfree program, or lead them to do so. When you do that, you're leading them to give up their freedom. Thus, what we should avoid most firmly is leading or encouraging others to run nonfree software. (Where the program uses a secret protocol for communication, as in the case of Skype, your own use of it pressures others to use it too, so it is especially important to reject any use of these programs.)
