Even if the counts are private, counters create an ulterior motive beyond substantive discourse in the desire to collect likes. Their signals constrain speech as posts are authored. Just like the profit motive, the like motive greatly skews reality from beneath the surface of what is being said.

And to disagree with someone, you should have to at least open your mouth. That's a conversation. To just be able to dislike or downvote let alone anonymously is harmful for everyone, even the person downvoting. Instead of exercising speech, it's a slap on the wrist response.

Removing context removes nuance, and removing nuance removes intellect.
