There seems to be some intention in this article to neutralize some of the pumpy and hype of Ethereum, DAO and to kind of equate "Blockchains"...

In other words, it seems to fail to recognize a true superiority of bitcoin and the fact that a lot of alts and a lot of private "blockchains" are engaging in deceptive practices because they are trying to ride on the coattails of bitcoin while failing and refusing to either give bitcoin proper credit nor to couple their investments into the bitcoin ecosystem.

Bitcoin is very likely to win out in the end, even while some of these folks seem to engage in false equivalencies and distractions.... at the same time, on a positive note, likely various bitcoin developers can likely learn from some of the "innovations" to the extent that there are any that materially matter of various competing blockchains.
