Unfortunately the people advertising lemmy on reddit and elsewhere rarely link join-lemmy.org, and direct people to join a few large instances. So we'll likely keep having centralization problems for the forseeable future.
lemmy-ui's default is to use the browser light/dark-mode setting. So you are likely looking at servers that have a custom theme without light/dark modes, or some hacked-on css.
I have a PR out for this now. Keep in mind that we're usually too busy developing to keep up with a lot of these posts, so its always better to create an issue for feature requests / bugs.
I can't take any credit for that one. A few months ago I put out a request to various rust programming communities on lemmy, asking if anyone could help make a rust library to use the clearurls data.
Thx! I'm its original creator, and used it to teach myself android app programming. It also has another core maintainer, mv-gh, who knows much more about android development than me.
I haven't had too much time to work on it recently, but its open source so anyone can contribute.
Lemmy.ml will have around 1-2 hours of downtime tomorrow, Friday at 1430 CEST.
We tried several things but weren't able to diagnose the specific problem, but we've narrowed it down to a specific file. We're keeping track of it in this issue. Most likely its gonna be one of those extremely simple things that got missed.
Thx for being patient, we'll probably have more downtimes in the future as we need to test more fixes.

The other ones aren't for collaboration and issue-tracking, just other places to make the source available.
