(IMO) It’s not so much that he is pro -ASIC it is that from his words he (believes) gives off the impression that because ASIC’s are setup to mine one set algorithm, and since Zcash is the most profitable of that algorithm, anyone who buys one will be using it to mine Zcash. They purchased it for mining Zcash, and did so to support the network and cause. Where as GPU miners can switch to just about any algorithm at anytime and therefore are not truly supporting Zcash.
Something he may not have looked at is the consistent network difficulty of Zcash, and the amount of gpu’s(?) that are always pointing at it. Unless there are ASIC’s already mining Zcash, the hard liners he wants supporting the Zcash network are already here.
