The claim "even 1 bit of bias on a 256 bit nonce value can be enough to attack certain cryptographic schemes" is true but there have been no practical attacks against 256 bit secured schemes. And the example of the mod 107 issue only reduces the amount of bits from 6.74bits to 6.71bits (a reduction of 0.4%) so hardly worth worrying about in the real world.
