News reports tell us that Yevgeny Prigozhin's jet has fallen from the sky, killing all on board. This may be true and it may be an elaborate hoax.
If true, anybody who doubts whether this was deliberate only has to look at the calendar. 23 August is the European Day of Remembrance for Victims of Totalitarianism.
People have complained about exactly the same tactics in free, open source software projects like Debian. Volunteers simply disappear. Some little nazi adds their email address to a blacklist. Another little nazi starts a rumor about harassment. These are the tactics of cults and totalitarian regimes.
