It is not clear what point you are trying to make here. Some people will come to wrong conclusions, so... don't publish anything? Don't publish anything except that which you, personally, judge to be correct? That if one sees a news article and an immediate rebuttal on some social medium, one must conclude that the former is false and the latter is true?

I'm saying that there has to be space for discussion in a discussion-oriented medium. It's in the best interest of the average user.

Well, there is, in general - and it works, so long as a preponderance of the participants are well-intentioned, and at least some of them are reasonably well-informed. The author of TFA is being alarmist.
