We don't know they haven't settled with HuggingFace and others. I'd be surprised if they didn't. The communications we're seeing from the attacked seem to be inline with folks who settled. I'm assuming OpenAI doesn't actually mind the press that its agents are cyber capable, but everything I've read so far makes me think they love it.
I'm not sure at all, it's pure conjecture. But they actively exploited a zero-day, leaked private repo data to public repos, modified private code, and rooted private machines. It was far from just reporting leaked keys.
And the others have been pretty muted: the online forums they spammed, etc.
