Whonix does not have a XMPP room, and if you ask an individul person, they may not have all answers but as you are sending the message specifically to them, they may feel obliged and discomforted to respond…
Not trying to say nobody will be friends with you on XMPP, just saying that you should not wait for that to start your journey.
It’s pretty difficult to explain to non-developers what was implemented by the Kicksecure / Whonix project and what wasn’t in simple terms. Easy to mistakenly underestimate or overestimate.
We stand on the shoulders of giants - Whonix ™ and many other Libre software projects are only made possible because people invested in writing code that is kept accessible for the public benefit.
Countless freely available software packages such as Linux, GNU, Debian, Xfce, Tor and thousands more weren’t created by the Whonix project.
