Yeap, she was famous on the west for her anti-russian publications.

But in Russian she was not famous. Moreover, there were found falsifications in her books.

But, as you have pointed here, her anti-russian publications were well paid on the West, and she got many grants for her job. Experts say, that she got only officially about 1,5 millions $ of grants.

So, she was much more famous on the west, than in Russia. And that is one more argument why the West was interested in her murder for pressure on Russia.
