Depends where you are. Quite a bit of the world's media supports rightwing parties. In any case, is "MSM" even a meaningful term, or just a catchy new internet trope beloved by those on the political right?
Plus a lot of the media openly sides with major political parties, donates to them, and even influences election outcomes in so-called "democracies". If you control public opinion, you effectively control the country (or at least wield a huge influence that you weren't elected to hold). Bit strange for some of those parties to then bemoan the media, when they often literally are the media.
If you ever want real democracy, you need to do something about the power of the media undermining said democracy. I probably agree with you on that, just not on the specifics.
