If this helps refocus the mining crowd to ASICs instead of GPUs why are you so against that? It only helps. ASICs are far more efficient than a regular PC doing the same work. Even if it takes longer to mine in this context, it'll still use less power and do it faster.
It's clear from this that you don't understand mining at all.
First of all, it's worth pointing that SHA-256 is what's used by Bitcoin and is already being mined only by ASICs. Most other coins attempt to be ASIC-resistant, in order to reduce centralisation and allow "the common people" to run them at all. Not that it's hugely effective at reducing centralisation, but it's better than what Bitcoin has.
As for the idea that lower power leads to more efficient mining, that's where it's clear you just don't get mining.
Mining is designed to produce blocks at the same rate. If more processing power is put into it, the difficulty of mining rises, so it takes more processing power to produce the same blocks.
Since the only point of mining for miners is to produce money for them, it doesn't matter how much power an ASIC takes, because miners will simply run as many of them as is profitable, reaching the same power budget.
The end result is that the same number of coins will be produced using the same amount of power, just using the fastest, most power efficient ASICs. So Intel isn't improving the situation by any means, only making sure that it takes the profits from mining chips instead of other chip makes.
Square is a corporation, not a miner.
Square is a corporation which has stated an interest in creating a Bitcoin mining facility, and that's presumably what this chip will be used for. All the others are also mining Bitcoins. These chips have absolutely zero value outside of mining Bitcoin.
