Because it doesn’t work. No matter if they say to upvote unpopular opinions, humans generally want to upvote things they agree with. So it can’t be an actual unpopular opinion. So people start to word popular (or at least not supremely unpopular) opinions as though they’re unpopular, get upvotes, repeat.
Hmmm me and my twin had an imaginary triplet. I don’t know what he was upto now. Or how he was identical to us when we always called him him when we are not male, generally.
I feel he’s doing well. He was our evil triplet, so this economy he should be doing great. Thriving and stuff.
