I agree, and I think it's a shame it has gotten to this point, but I understand his viewpoint completely and have seen the interactions myself. At this point it's simply more efficient to promote Piefed on Reddit instead of Lemmy, because you want the absolute least amount of friction for potential new users. Literally any single minor inconvenience/negative thing will cause people to not even consider trying it out. Lemmy has unfortunately already accumulated a reputation, and if you promote it you are very likely to run into comments about tankies which is typically enough to scare potential new users away.

At the end of the day it shouldn't matter to us which software people use, as long as we get more new users into the ecosystem.
