Thank you for your thoughtful discussion with me about this earlier skoki.
One consideration that is important when considering bias (individual, group, media, etc.) is that we all have one. We all have our perspective, influenced by thousands of tiny moments in our lives, and sometimes this is going to lead us to inaccurate conclusions. Being somewhat aware of this and trying to test testable ideas, and get wider perspectives are always helpful in addressing our own prejudices.
However, it is also important to note that this does not then mean every source of information is equally biased.
There is a difference between someone deliberately trying to tell one story, and someone whose main focus is remaining factual.
There is a difference between saying, this source repeatedly proves inaccurate, so we will not let it spread propaganda so easily (but you can still access it if you chose to look it up) and someone with power to physically harm / restrain you (e.g. police) being authorised to ensure that no counter-opinion is offered.
It is bearing that in mind that helps me consider that the bulk of news media available in Russia is controlled by Putin is a factual statement. That does not mean that they say nothing true, but they are severely limited in how they may talk about things, due to the negative repercussions.
