I suppose if you had one RNG that's 0wned by the NSA, and another that's 0wned by the Chinese MSS, and another by the Russian FSB... and you assume they never ever work together or crack each others' systems, you could XOR their results together.
Unfortunately, the debate is mostly centered around if crypto is broken, while the question to ponder is why is the state suddenly forcing well-meaning people to start thinking like people who have something to hide.
