I was unpleasantly surprised a year or two ago when I realized that part of Bitfury's R&D was into blockchain analysis. It should come as no surprise that blockchain analysis is maturing as so much money continues to flow into Bitcoin and other coins.
But naturally, I no longer view Bitfury as a company to root for. They're working with the enemy now.

There are other coins for some less public transactions, Bitcoin was never meant to be, and it's fine that way.
I don't think that's entirely true. I think that the privacy implications weren't entirely clear at the outset. The norm of using change addresses (including multiple change addresses per transaction) was obviously privacy-oriented. I think the point of Bitcoin's design was transparency, but I don't think that Satoshi necessarily intended for it to degrade user privacy.
