I’m not sure there’s a purpose to it the way things are clustered here. Particular for anything of a political/news nature the very same post on one instance and com may get a completely different reaction on another. There are a fair number of people that I think of as ‘fire and forget posters’ in that they simply fire off posts but rarely interact with them after. Making this the default would likely encourage more of the same behavior, possibly leading to more spam.
More a speculative thought, but if those who do pay attention to negative feedback no longer see any, they may not take that into consideration when they put things up.
Say someone put up a post, saw no backlash on the front end, but then comes to look at the responses and sees a cesspit of hate. That’s hardly going to soften any mental harms it might otherwise impose.
Another thought here is messing about with such things, particularly in making them a default behavior, could disrupt comms where there is a strong voting aspect to it. The ‘am I the asshole’ type place that, despite the usual attempt to have them adjudicated by some nuanced comment system, inevitably end up using votes as a agree/disagree dynamic.
