Who can say? I am of a similar mind, I’m not holding out hope that it will be much more than a dumpster fire. But I think it’s at least worth seeing what happens before taking the nuclear option of defederation.
If things are shit all over and Lemmy.world still decides against defederating, there are plenty of instances that already have, so no skin off my teeth either way. I can always just sign up elsewhere, or even just host my own. The beauty of the fediverse is that you never have to feel stuck with things as they are.
I’m just giving the benefit of the doubt to the smallest possibility, however unlikely, that another influx of users might bring at least a bit more activity to some of the Lemmy equivalents of niche communities that I loved from Reddit.
But I’m also not the sort of person who is kept awake at night by the fact that thousands of people are about to be gifted PCs for Christmas that run Windows out of the box instead of Linux, so I suppose I don’t have as much to lose as others when it comes to having more normies show up.
