I agree about the danger of disinformation. But writing a law and claiming it combats disinformation is not the same as combatting disinformation.
In Russia today you can go to jail for up to 15 years for stating that Russia is at war. Why? According to the ruling powers this is disinformation. It doesn't matter that they are lying and you are telling the truth. What matters is that they decide.
My point isn't that there can be no law combatting disinformation but that you cannot take the authorities' claims about their law at face value.
Full democracy needs allowing people to think for themselves and spread their ideas freely to whoever will listen. Full democracy is not compatible with telling people what to think.
We steer clear of laws that are dubious and ambiguous because they can be leveraged whimsically or loopholed.
But ignoring threats to full democracy (disinformation) is just as dangerous, if not more dangerous.
