I feel like we need to talk about Lemmy's massive tankie censorship problem. A lot of popular lemmy communities are hosted on lemmy.ml. It's been well known for a while that the admins/mods of that instance have, let's say, rather extremist and onesided political views. In short, they're what's colloquially referred to as tankies. This wouldn't be much of an issue if they didn't regularly abuse their admin/mod status to censor and silence people who dissent with their political beliefs and for example, post things critical of China, Russia, the USSR, socialism, ...
As an example, there was a thread today about the anniversary of the Tiananmen Massacre. When I was reading it, there were mostly posts critical of China in the thread and some whataboutist/denialist replies critical of the USA and the west. In terms of votes, the posts critical of China were definitely getting the most support.
I posted a comment in this thread linking to "https://archive.ph/2020.07.12-074312/https://imgur.com/a/AIIbbPs" (WARNING: graphical content), which describes aspects of the atrocities that aren't widely known even in the West, and supporting evidence. My comment was promptly removed for violating the "Be nice and civil" rule. When I looked back at the thread, I noticed that all posts critical of China had been removed while the whataboutist and denialist comments were left in place.
This is what the modlog of the instance looks like:
Definitely a trend there wouldn't you say?
When I called them out on their one sided censorship, with a screenshot of the modlog above, I promptly received a community ban on all communities on lemmy.ml that I had ever participated in.
Proof:
So many of you will now probably think something like: "So what, it's the fediverse, you can use another instance."
The problem with this reasoning is that many of the popular communities are actually on lemmy.ml, and they're not so easy to replace. I mean, in terms of content and engagement lemmy is already a pretty small place as it is. So it's rather pointless sitting for example in /c/linux@some.random.other.instance.world where there's nobody to discuss anything with.
I'm not sure if there's a solution here, but I'd like to urge people to avoid lemmy.ml hosted communities in favor of communities on more reasonable instances.
As you say OP, the solution here is to use the fediverse model as intended and use different instances/communities. It sucks because it fragments the community, but that’s the way it is. I’ve long held the opinion that I’m grateful to the lemmy developers for building this whole thing that we all get to enjoy, but their approach to administering an instance is reprehensible and actively damaging to the relatively free and open exchange of ideas that should happen on the fediverse.
The threat is bigger than that though. These people control the code base and can easily just start running modified code to fuck with various aspects of federation to generally keep their finger on the scale of any instance which federates with them. At best they have shown they have no shame and cannot be trusted. If there is any means of abusing their power, it must be assumed that they will embrace it.
People are working on alternatives - Ernst started Kbin and then kinda got stuck in it but refused to allow others to help so a community fork Mbin was created, and sublinks will eventually exist as well. However, this stuff takes time. You can help by contributing code or funds or activity to one of those if you like.
