There are some of the (endless) examples of state level interference elsewhere on this site, but don’t believe us. Don’t believe no one. As Mr. X tells Jim Garrison (JFK film):-
“Don’t take my word for it. Don’t believe me. Do your own work, your own thinking.”
This is the most important take away from here. Do your own research and form your own conclusions. Read around. And so this section ends with some other thoughts that every good cryptographer should keep in mind:-
“A lie told often enough becomes the truth.”
“Propaganda works best when those who are being manipulated are confident they are acting on their own free will.”
And finally a comment from a popular Q&A site that neatly sums up conspiracy theories:-
“My problem with tinfoil hats is that conspiracy theories are almost always utter nonsense.”
All of this boils down to the risks of using randomesque numbers generated by others, rather than true random numbers created by yourself.
