I feel like TFA answers the fake insurance question pretty well. The company sold "insurance" which was not actually insurance. They were providing a cover for ships selling from a sanctioned country. Those ships were required to have insurance, and no legitimate business would insure them.

Because, firstly, this is a university, not some rando self-hosting, and secondly, you can't generate randomness from any classical computer, only pseudorandomness [0]. This means that a dedicated adversary can potentially work out what the outcome will be. For something like the use cases they mention - jury selection, lottery, etc. - you want actual randomness.
