I never argued that misinformation doesn't exist or spread. I argued that what you're classifying as misinformation is wrong, and that you can't quantify any of the alleged negative effects of it despite qualifying it as dangerous.

The spread of disinformation is due to a network of activities

That network of activities is called the free exchange of ideas and it is by far the most powerful tool for open discourse and truth discovery. We are both able to discuss these "dangerous" issues like adults without either of us dying of covid or requiring an authority figure to "correct" classes of speech they deem misinformed as if they are the gatekeepers of truth. These same gatekeepers have been consistently factually wrong.

"Dangerous misinformation" has existed for as long as discourse has. It has existed in the town square, in the newspapers, on mainstream media. It has existed since the internet became popular. It existed 15 years ago when free speech was culturally supported and championed by the left.

It has never been a problem before. It only is now because authoritarians see an opportunity to crack down on free speech under the guise of protecting people from themselves. There are seemingly plenty of people who would happily give up their innate freedoms for the promise of a safety that can't even be quantified.
