I'll take this opportunity to mention that I don't think the DHS press release should be taken as "authoritative" on anything other than the government's intentions. As you point out, the administration is being wonderfully clear that they intend to make an example of Harvard and punish those who would side with them.
I'm glad that despite being immediately being voted to a negative score and pushed to the bottom, some people like you are reading the link. If the goal is to understand what Harvard is up against, I think it's really useful to read what the government is actually claiming. I wasn't expecting that many people here would be persuaded by it!
