It's a propaganda piece. Clear as day.

The Zcash devs are most likely not even interested in any rebuttal.

The only purpose of the piece is to exist as an easy to remember URL that can be routinely dropped into conversations pertaining to XMR from a SNARKS perspective. The question that most fatigues the SNARK developers at conferences is "Is it better than Monero?" to which the obvious answer is actually "No, it's not." However as recent reports indicate, these type of questions are often smeared into oblivion with retorts such as "Monero is a bitcoin clone" and other opportunistic gems targeted for an audience who don't know better. The existence of an easy to remember URL that can dazzle aforementioned mindless targets is all that this piece is really intended to be.

And you can bet any money in the world, Joel Valenzuela (aka Ass Clown of the Year) is already tapping away at the keyboard preparing another follow up piece for the CoinTelegraph.
