I believe you are lying, or at lease presenting the information and options in bad faith. If your goal is to teach people how to use more private communications, then a 3 minute video full of subjective options on "speed" and "extremely easy to setup" of XMPP vs the "buggy-ness" or "slowness" of matix dose not teach anyone anything.
A video with only positive things about XMPP and only negative things about Matrix isn't a good "comparison" video and smells dishonest or like a scam to me.

also there are links in the article but they only link to more pages on your own website and not to matrix.org or xmpp.org where someone could go to learn more about the programs or how to set them up.
