Claude is not as ideologically willing as friends of the Trump administration are - like xAI's Grok and OpenAI's ChatGPT. And David Sacks, the AI czar, who is a PayPal mafia member and close friend of the Epstein class (Elon Musk, Peter Thiel), has been attacking Anthropic FOREVER. He views them as a woke threat to America. So all that supply chain risk and the ban from agencies is just a way of abusing power to suppress free speech.
But the most obvious reason, is that Greg Brockman - who's a founder and also the current president of OpenAI apparently, is the largest donor to the Trump MAGA PAC. I find it hard to believe that Sam Altman and the Trump administration would be so obvious about it, but I also find it hard to believe that tens of millions in donations and this kind of result can be anything but a bribe.
