I’m asking this because one time, while browsing the GNU website, I noticed that some of the members’ emails had “gmail” on them!! And I asked myself how would that be possible?? And I think other members of the FSF had Gmail too. Why? Richard Stallman is against Gmail, so why would those memberse use it?? Would that mean I can use non-free software while advocating and loving free/libre software??
but Richard Stallman himself uses a completely free (libre) laptop and even his GNU/Linux distro is 100% free, so he is living by his example!! But ok, can I still use Discord and promote free software?? Woa >u<
Use whatever you like, there is no rule book that says you have to do this or that.
The goal is freedom, right? Be free.
