I'm not in complete understanding of what differentiates a true random number from a non-true one in this instance.
I fully understand why algorithmic pseudo-random numbers can be said to be not 'true' random numbers -- if you know the algorithm that produces the numbers, and you know enough of the numbers output by any particular 'round' of random-number-generation production, you can in principle figure out how the algorithm was seeded -- or narrow it down to a few possible seeds -- and predict with greater accuracy its future outputs. (I'd like to know if I've got that wrong).
But in this case, that doesn't seem to be a concern. What could make someone think it's an 'un-true' RNG? What, to such a person, would a 'true' RNG look like? Is thermal noise an 'un-true' RNG? Why?
Some hardware RNGs had poor deskewing or correlated bits or no failure detection or were outputing other non-random noise or were using weird sampling rates.
I post a link elsewhere in the thread with some description. RFC4046 has some more information.
So, while the hole-electron moving[1] through the pn junction is quantum there's a bunch of other stuff that can be sent to the output stream and that poor software implementations include as random.
[1] apologies to physicists for inaccurate terminology. I never really know how to describe what hPpens with holes and electrons in semi conductors.
