It can be a bit confusing due to the terrible style of the article (ironic given the source) but it seems the "sketchy russian website" part is a direct quote by Anthropic's Sam McCandlish. And apparently Dario Amodei referred to it as sketchy as well.

They didn't believe it was sketchy. They were just worried that the commentariat on HN will frame it in a dumb, manipulative way like that.
Judging by how AI threads look like for the past year, they were absolutely right to be worried.

Especially the courts.
