Unfortunately it isn't always cut and dry. As the GP pointed out, once upon a time the heliocentric model was "disinformation".
In more modern times, suggesting that the Gulf of Tonkin incident was misrepresented would be "disinformation". Suggesting that we didn't need to invade Iraq to prevent another 9/11 would be "disinformation". Sometimes yesterday's "harmful disinformation" is simply today's "information".
I think the ethical question you presented is multifaceted. On another axis, do the people who control the most prolific video platform also have a moral responsibility to ensure a free society has the tools to ask difficult questions?
