In a funny way, even the comments on the post here don't match what the post actually says. The writer of the post tries to frame it as an attack towards open source, which is honestly a hard to believe story, whereas the comments here correctly (in my opinion) consider the possible problems Chinese influence might pose.
Yeah this blog post seems pretty misleading. The first couple of paragraphs of the post made a big deal that the NIST report contained "...no evidence of malicious code, backdoors, or data exfiltration" in the model, which is irrelevant because that wasn't a claim NIST actually made in the report. But if all you read was the blog post, you'd be convinced NIST was claiming the presence of backdoors without any evidence.
