I still think staked polls are useful as a community organizing tool, even if there are reasons to not treat such polls as dispositive.
Before deciding whether to launch Ycash as a chain fork, it would have been very useful as an organizing tool to have some information about whether ZEC holders (weighted by amount of ZEC, as of the summer of 2019) supported a fork that would change the Equihash parameters and honor the 10% cap on coins not allocated via the mining process.
If such a hypothetical poll had shown adequate support from ZEC coin holders, it would have helped in recruiting more people to help with the chain fork.
If such a hypothetical poll did NOT show much support from ZEC coin holders, that too would have been useful. It would have suggested perhaps that ZEC users who care about such things either never existed in the first place OR left the community (and sold their ZEC) in 2018 in response to the ECC not changing the Equihash parameters. It may have led to Ycash being launched as a code fork with its own genesis block (not a chain fork of Zcash).
Finally, the debate here reminds me of attorneys arguing that certain evidence should be excluded on the basis that it is so prejudicial that the jury should never see it. I believe community members here are wise enough to review the results of staked polls and decide for themselves individually how much weight the results should be accorded.
Thank you @amiller for providing this poll.
