If there is disinformation, the solution is to counter it with actual information, to give the people better tools to identify it (like X's community notes), and to educate the general population so they will have better critical thinking.
Restricting freedom of speech is never a solution. How long until dissenting opinions are censored because somebody labels them "disinformation"? Who watches the watchmen? etc.
I'd rather live in a society with full freedom of speech and disinformation from State actors than have only 100% accurately vetted news.
