Anthropic has the appearance/rep of being non-cooperative with the military industrial complex.

OpenAI doesn't have that reputation.

That's all.

This. Anthropic made at least some token effort to imagine a future where AI and humans cooperate in a constructive way and AI is not used to harm people intentionally. They learned their lesson.

Exactly. OAI didn't bury themselves. They didn't have to do anything special for this, they just had to let Anthropic be Anthropic and sit on the sidelines.
