@eschatosoof@theres.life you are right, my friend!
That's why I teach online. Then slowly, I see many of people in my country switching from WhatsApp (and switching to GNU/Linux as well as that is my course actually) as the requirement to join is one must have #Telegram and #LibreOffice. I run this since 2017. I can say it is not pointless.
Glad to share with you!
