It looks like this was a larger decision from the lemmy development community in an attempt to eliminate karma farming. They say it’s psychologically damaging, and as someone who looks at them a lot, they may be right.
Here’s a GitHub thread discussing it where our Voyager dev weighs in:

I‘m frankly not sure what I should think about that. I get the argument of chasing points being harmful, but I would imagine that it also drives interaction and gives some motivation to participate – and Lemmy definitely benefits from participation. I also like myself some reports and statistics.
