There are some of the (endless) examples of state level interference and cock-ups 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. Be skeptical. Do your own research and form your own conclusions. Read around. Experiment. Randomness is too important to leave to web sites found by chance. Then experiment some more. And so this section ends with a few other thoughts that every good entropist and cryptographer should bear 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 created by others, rather than true random numbers generated by yourself.
