I agree. As of very recently, a VERY large proportion of my comments have been downvoted, and some of them even went greyed out. I used to often post against the grain of broad consensus of the site (think: the "Tenth Man" style rule, whether it's fictional or not) to inject a perspective of someone from a very different background. Nobody had a problem with that. It's as if people are far more irritable these days and just won't engage with the comment beyond hitting the downvote button.
For the anti-tech and pro-regulation sentiment, I admit I've been a part of that. I cannot disagree that hundreds of posts saying the same thing are monotonous, but I cannot bring myself to criticise it because then I'd be silencing a PoV that is mine.
