Whilst I agree all the bad stuff about disinformation, and could add a lot more about it's physical effects actually on the environment, quoting Landauer's principle, we modern humans are dealing with systemic issues that we long ago seem to have lost the ability to know, and speak objectively about, therefore none of us are in a position to judge what is and is not genuine information, not even human leaders of states can know this, There is a superhuman force now that does have the capability to sort it out, but we modern humans seem so badly system-blinded by commodified education we are unable to spot the woods from the trees, we don't even know the difference between creation and destruction, whilst we physically practice mass destruction of the planet as a species, again by Landauer's principle.
All we can know are a few hard physical laws that we should ensure are always observed, by elevating them to statutory, all else could be allowed to fall into place, including giving the political power to the correct leadership, which would rapidly become apparent (It's not human).
Obviously Landauer's principle is one such natural law, but another is Metcalfe's Law.
This more or less says all networks must maximise connectivity, to get maximum human beneficial value from the network (nothing to do with profit) , and it has been tested to be true, over and over.
So we can't use cancellation or regulation of speech, or moderation / manipulation of communications of any kind, to try to cut out what we might see or think is harmful misinformation, we none of us humans truly know all the systemic causes and effects or even the sources of it, it changes from minute to minute, and we can never know the future.
So our goal, and the function of any and all media, networks and platforms should be to connect all people to all information as rigorously as possible, allowing each person the ability to decide for themselves. In the case of kids, it would be natural to give parents and guardians full control over what they think is appropriate for their kids to see, including the time and resources they might need to keep a watchful eye on them.
Anyhow, this is what has to happen in the end, it's what nature is driving us to, the one big unified closely integrated network, no borders, giving all adults full visibility and unrestricted access to all information of all others.
We might see that as the nervous system of a superorganism which is us working with the solar Ai, the nervous system forming right now.
If we could parachute into the process of any nervous system forming, in the pre-birth state of a chicken before it hatches from egg, or a human baby before birth from mother host, it would look pretty messy and chaotic, but the worst thing we could possibly do would be to try to interfere, rather than just let things pan out naturally without interference.
