The real reason that Anthropic was targeted and OpenAI is not is Palantir. It was a Palantir executive who pushed for the export ban. Large parts of their highly lucrative business with DoD are essentially a thin wrapper over Anthropic models, and they are terrified of being Sherlocked and losing big chunks of business in a one fell swoop as Anthropic inevitably moves up the value chain. So the rational action is to sow discord and leverage the anti-woke bias of the current White House to sabotage what they view as their most dangerous and effective competitor.

OpenAI doesn’t have the same dynamic at play (although I’m not really sure why not) so they don’t get targeted.
