Gladly its not you to decide that, as sad as the situation is. And also as sad as it is, the Hitler comparison is still inappropriate in both directions, please refrain for dignity.
Order vegetarian or ither special option, get it usually first and probability of someone doing the same nearby is low, and then eat like you haven't eaten for days before and put mask on before anyone else takes it off - worked fine for me lol.
Also keep ventilation from above right on you at least a little...
Much more frightening were all the people in queues at the airports, bad ventilation, coming close, not wearing a mask at all.
Why so scared? Same reason, didn't want to get even a single day wasted for the first and quite costly vacation, glad it all worked out!
Agreed to cryptographic snake oil, but in regard to Russian-controlled would encourage to read on the biography of https://en.m.wikipedia.org/wiki/Pavel_Durov and him opposing Putin and how Telegram has tried to just outrun any state control.
In that sense, I believe Telegram is much more independent than fully undermined FB/Whatsapp... but for what does it matter? Any public group will have leakers And can potentially be undermined by any big enough actor... either you are in a small fully trusted and encrypted circle, or you are in a big and always public group with potentially enemy actors?
