This is the crux of the issue. Legacy institutions are used to determining what is true and therefore what is inside the bounds of allowable opinion.
This was their domain for decades but it can now be seriously challenged by relatively few people due to the amplification in sharing of human thought through the internet.
Their degradation was the only outcome likely from networking so many individuals together.
'Disinformation', even if you are inclined to trust legacy institutions, should be viewed with a healthy degree of skepticism. Even if we grant that legacy institutions always had the closest approximation reality over the past several decades (and this is generous).
Everyone should now be able to recognize these players for what they are: self interested actors bending public perception of reality to convenient conclusions for their own benefit. Given this, it is not surprising that people are more motivated than ever before to uncover past warpings of past narratives. They are searching for their historical moment.
Now we can grant that it may be best to have these legacy institutions looking out for our interests rather than some unknowable future state of governance. But checking their past conduct is a textbook littered with dark chapters that is now being viewed with the understanding that these are the rosier sections. Not a good look. As we move forward in time the failings of existing governments will only become more apparent not less; and it will continue to make less and less sense to believe in them.
The alternative to this would be to either restrict information flow to some pre-digital age or to perpetuate totalitarian regimes in charge of protecting their own existence by manipulating the masses into passivity.
And here is the second crux, it is only the legacy institutions from the 20th century who are perpetuating the conflict. Were the doubters given license to control their own territory, we have every indication that they would leave the past well enough alone and forge ahead. But the 20th century just cannot let go its dreams of total domination of thought and reality.
