I guess being anti-crypto is virtue signaling now. Guess that means we're at the turning point where crypto isn't this cool magic money thing anymore now that the harsh light of day is being shone on the industry.

Or, I think more likely, is that the parent can't actually form a cohesive argument and is part of a group of people for whom the term "virtue signaling" has become synonymous with "bad" but is used to try carry more intellectual weight than it actually does.

They have forbidden crypto mining on their cloud services (i.e. shared cpu hardware) since it started, but until recently they allowed it on dedicated servers. Stopping it now seems to be a result of Chia having a real impact on their equipment availability and longevity. Chia has apparently also driven up the street price of large HDD's by a significant amount, 30% according to a forum post I saw.
