This article massively exaggerates the positive attitude Russians have towards women in tech. My Russian mother keeps telling me time to time that there must be something wrong with me that I have this genuine interest in tech things being a girl, because "all this physics and computers is not a girl's business"...

As some commentators already mentioned, Soviet Union tried to make no distinction between male and female professions. But nowadays social roles of men and women are strongly polarized and Stem mostly considered as not women's business.
