Is there such a thing as unbiased experts in crypto currencies?
Probably not, everyone has biases. But math is math, and if you show actual mathematical proofs, the experts will fall in line (and even build on top of your work).
For example, much of the cryptonote cryptography gets good reviews from people who are clearly biased toward bitcoin (gmaxwell being one well known example). They also come up with some very valid criticisms and suggestions for improvement (which we considering).
There could be two reasons why Bitcoin biased experts actually attempt to review cryptonote.
Because: a) they don't feel that their Bitcoin investments are threatened by CN cryptos; b) because cryptonote is also PoW, which falls in line with Bitcoin and reinforces faith in PoW scheme, both for themselves and newbies who only start looking into cryptos.
PoS is a totally different animal, and getting someone who has been a strong believer in PoW to review PoS objectively is a problem
because in case they find out PoS is safe and better, they can't back out of this, because then math would prove it, which means the status quo of their PoW investments would be shaken. So for now the approach is to stick the head into the sand hoping PoS would just go away by itself
