Is it acceptable to use proprietary software (platforms) to promote software freedom?

[Adonay Felipe Nogueira]

GNU Ring is P2P/distributed chat/text/video/audio/conferencing software,
see: [[https://www.gnu.org/software/ring/]].

It might be "not that stable" yet, but at least they (GNU Ring)
themselves got the initiative to seek inclusion inside GNU project, and
often talk more about free/libre software than open source. :)
