So there was 39 vulnerabilities that affected government systems. The rest didn't so they had no need to disclose.

Similar, but my thought is that they found out some other gov(s) know about it as well. And that it hurts others more than it hurts the US gov.

I'd say that's a very cynical take, theres a verification process and they disclosed 90% of them, pretty generous gift to the world if you ask me. They do not have a moral mandate to use their resources to benefit all.
