In principle this happens every day in the West, at least partially. It is most noticeable in US because here the political landscape is very polarized.

There are two important differences though.

The main difference in this case is that there is no monopoly and complete central control, like Russian leadership has over Russian mass media.

Second difference is that Western media does not have direct influence over other populations, if it decides to weaponize its mass media, it can only direct it against the people in their own country. Everywhere else it will be filtered by local publishers.

Russia has (or now in many instances, had) also media control over large Russian population in neighboring countries (like was in this example).

Asymmetry in freedom of press and freedom of speech works strongly in favor of malicious actors with strong control over media and speech.
