To me the beautiful thing about trying to get randomness is that as long as you have one random source then you have randomness. I.e. non-random XOR random => random.

So, you use X sources, as long as one of them is truly random then you are golden. Even if most are compromised it shouldn’t matter. Use on device security chip randomness, use user input, use external party providers etc. it all helps! (But be careful to errors when implementing, that’s hard to do!)
