Governments and big organizations obviously and demonstrably try to use mass media to control what and how people think. The EU has an entire agency (East Stratcom) dedicated to managing Russian news sources in Europe. The EU voted to further fund them further last month. I can't think of any government that doesn't actively fund some agency or the other for such purposes.
Governments try to use mass media to control people habitually and have done since the days of the printing press led to public pamphlets.
To try and play the "Conspiracy Nut" card against what I said is ridiculous. In the very literal sense that I ridicule you for trying it.
Do you believe in objective truth? The head of RT is on record saying that she does not.
If news organisations are being run on the view that everything is subjective then there's a huge risk that populations will become cynical and abandon the news as a source of factual reporting.
That is what EastStratCom is about. It's not about "controlling people" - it's about informing and educating them about the nonsense that's out there.
