I'm not sure how I feel about that argument, did we really just find a place where public attacks on a person are better? I would think at most people actually involved in something that relies on the person may have a valid argument for such a thing, if it sticks to a concrete subject they actually have reason to care about. Other than that, I don't see the general public getting involved in discussions of a person (as such, in general) as a good thing.
If I am trying to determine if I should buy or sell TSLA because the CEO just called another man a "Pedo" or claiming "funds secured" I think discussing what this man has said is justified.
