I read the article you linked:

I know that Anthropic claims that "large-scale coordinated "distillation attacks"" exist. They are not a disinterested party here and they don't provide evidence either.

Also you're just moving goalposts around. The article you linked also cites Anthropics claim but then paints a much much mor nuanced picture.
