" technology that are inherently predatory,”
What a bunch of nonsense. I suspect the real reason is more likely: they have a far-left bias on many articles and fascists/totalitarians etc can't survive when people are free for long. When there is free discourse and a monetary instrument that can't be as easily censored as bank accounts (see e.g. Canada) they, and their masters, lose. A technology that allows people to is decentralized and censorship resistant is unacceptable.
They are dissatisfied with the large consumption of electricity that is spent on bitcoin and ethereum mining, so they made such a statement. Let's wait and see what happens when ethereum mining ends.
