The core issue here is that there are too many things to do, and too few developers to do them. By the way, for a huge number of these things that need to be done, there is most likely at least one person who thinks it’s the absolute highest priority for Lemmy. Forking would not help fix this issue, it would only make it worse.

In other words: if you’re a Rust dev, you can just fix it in Lemmy anyway, so there is no benefit from forking. If you’re not a Rust dev, then after forking, you will have a new repo to create issues on, except you’ll have 0 devs to actually fix them.
