Yes, but my blog is not about Zcash. It is about the Zerocash technology (employed in Zcash and clones) which I propose to use in a different design that I claim mitigates those disadvantages and allows the advantages to shine. Details were discussed with jonas_h, discussed with JollyMort, discussed with @smooth, and I referred others to these discussions.

Thanks for pointing this out, so I could provide clarification.
