Hello,
multiple times i have seen Telegram links on this forum. You may not know but Telegram is a security-nightmare: Telegram-Groups are not encrypted! And what's about the occurring metadata? Please consider to stop propagating of Telegram-links. Dr. Jörg Wurzer should not use such a bad way to even announce news eg. findings on new VollaOS version. Instead you could set up a Signal Messenger Group. You are already providing a cell number / mobile phone number on the Volla webpage, so you could also share a Signal-Group link. Maybe it is necessary for Volla to provide a Telegram contact, but please do not encourage security-oriented users to use Telegram.
