The problem with this declaration by the government is that now any company doing any business with the US government would be effectively forbidden from using Anthropic ANYWHERE within their company, which is a huge deal, because the government does want to vet any vendors' software development practices.
But as long as the Judge in this case pushes back against such an action by the government, that leaves companies free to use Anthropic for their own internal uses. And most companies WILL continue to use them if it makes economic sense.
