I mostly agree with you, but this one:

"- so controlling they are the only US company blacklisted by the US government"

They were blacklisted by the US government because they didn't bribe Trump. While all the rest of the tech elite lined up to siphon a few million dollars through various Trump grifts, Anthropic sat out the inauguration, the ballroom, etc. Then, when they mildly pushed back on surveilling US citizens with their technology, the administration banned them on that pretext.

If there's any evidence Anthropic is one of the better actors in an industry full of bad actors, that's it. They have nothing to be ashamed of in that particular series of events, as far as I can tell.
