Simple rational argument:

SCOTUS says POTUS is above the law, so POTUS has collected $4B in bribe / protection money since taking office 13 months ago. Anthropic has lots of money at the moment. Why should they be allow to keep it?

Since they didn't pay off the president (enough?), his goons are going to screw with their revenue and run a PR smear campaign.

Once you realize it only has to do with Trump's personal finances, and nothing to do with national security or the rule of law, then all the administration's actions make perfect rational sense.

Open question: How much should a congress-critter charge Trump for a favorable vote? (The check should come with a presidential pardon in the envelope, of course...)
