I think the article is exactly opposite in what people should be doing.

My advice: avoid positive echo chamber, unless they reveal genuine behind-scene facts.

Negativity is never a problem, people routinely sacrifice a lot for meaningful objective and reasonable leaders. When they turn negative, it's primarily there isn't a positive feedback loop in the environment.

But what's really happening now is that people are instinctively sugar-coating their meaningless job to lure outsiders for their own ego or whatever.
