Dead Man's Switch is a common trope that coexists in real life. See also: Julian Assange / Wikileaks in 2016. I seem to remember that one had a death scare, keys released, checksums on the payload(s) changed and all sorts of shenanigans surrounding it ultimately culminating in nothing. I didn't follow it closely at the time.
Wasn't there also a big kerfuffle after Epstein Most Assuredly Committed Suicide one of his larger residences was cleaned out before the FBI (supposedly) got there? Why dump all the video evidence on the public when you can be the one to cash in on that sweet, sweet blackmail instead of Epstein/Maxwell. Meet the new boss, same as the old boss.
