Hello all, I was wondering what free software was used to communicate with Edward Snowden during the Libreplanet 2016 keynote. I want to be able to keep in contact with some friends while I am away over the summer, but I refuse to use Skype, WhatsApp, etc. I would like to know how I can setup video chat communications between people that does not involve proprietary software. (Bonus points if it is easy for a newbie to free software to setup on any major operating system!)
