It's just a case of different opinions, I think. Or perhaps they think reddit having 100's of millions of users is creating the problems, and that they won't exist here if those same voices came to Lemmy. But I would mostly just say it's two different groups of people asking for two different things.

I'm in the boat that Lemmy has fully replaced reddit for me and I don't feel the need to go convincing more people to jump ship. The people who cared about the health of Reddit as a platform have already come to Lemmy, the people who don't, or need the massive userbase to use a website? They can stay there.
