From @fsf on the "Blue Bird"

With an associate membership, you can start a #Jitsi room and invite whoever you please, whether or not they have an #FSF account. You're not handing over your credentials to #Apple or #Google by proxy. Unlike the flagship server, ours does not require a third-party login. It does not use nonfree #JavaScript, and it does not recommend nonfree software or #browser #extensions. https://www.fsf.org/associate/about-the-fsf-jitsi-meet-server
