This is breathless but misleading. With recent conservative judicial decisions the notion of general privacy is on the ropes, but KYC has always precluded financial privacy at any scale other than unstructured cash transactions, and you're still supposed to report those in your taxes. This is in line with the treatment of other entities that fail to maintain KYC compliance.

The state has the power to levy taxes and prevent transactions with entities that it considers harmful (OFAC is effectively this); this is the state taking steps to do so, while GitHub is deciding that people who are attempting to evade those laws are outside the risk profile of "who we want to provide services to".
