It never really was. Reasonable conversations were being had, just not on polarized platforms. People's knee-jerk reactions to downvoting and "cancelling" every thing that mentioned it, in good faith or bad, last year was a direct response to the powers-that-were choosing the "China did it (maybe on purpose)" narrative to misdirect peoples anger and frustration.

If those same people would have said things like "obviously, it's _possible_ it was leaked from a lab, we're going to work on finding that out and let you know what we find as we do. In the mean time, here's what we're going to do about the immediate problems we're facing..." and ended it there, there wouldn't have been any backlash. That's what going on now, and that's why this post (good or bad, I can't say, I can't access it) wasn't flagged into oblivion the second it hit the front page.
