@ansuz One thing for you to think about: if a Russian randsomware gang scoops up all the data of a sellers of schoolbooks (as happened here in Belgium) which includes names, addresses, phonenumbers, names of parents, .. count on the FSB to get a copy of that data. I'll leave it up to you to image what the concequence of that could be if you have a job in encryption

Cybersecurity is the responsability of everybody, not just the coders.

I completely agree with your remark on the Flipper zero. 🙄
