It's amazing to see people casually use these words as if they still have universally meaningful definitions. Not anymore. What one half of the country considers misinformation another half of the country considers the truth. Not to mention that social media operates internationally.
You can't have a meaningful discussion without admitting this and doing something to escape the semantic trap of perfect ambiguity. In other words, you first need to establish some sort of information processing principle that is unambiguously defined and everyone (or at least the wast majority of people) agrees with.
