I think a big part of the problem is that the exodus happened in waves. Some people were on Lemmy for ages. Others came over when Reddit announced its API charges. Others came when Spez did his AMA. Others during the blackouts. Then finally there were the people who came over when the apps stopped working. Each of those people come over with fresh wounds that they want to talk about, but for the people who were among the first to come over it can get a bit tiresome.
