Re: Zcash Minus 20% "Genius Tax"

Suprnova Mining Pools controls over 51% of the mining power on Zcash.

It is trivial to remove the 20% Founders Reward in Zcash with a hardfork, as I describe here.: https://medium.com/@heyrhett/zcash-miners-stop-paying-20-genius-tax-486d9f40884f

this is really so easy? why wouldn't miners do this. and what happens afterwards? what will the devs do after the hard fork?
