Yes, unfortunately, some of the largest communities are still there because .ml is the home instance of the Lemmy developers. That's a real problem.
Recently, one of the mods there deleted two comments I made out of the blue – I had simply said that, in my opinion, there can be no justification for terrorism against civilians (I don't see what's wrong with that). I already knew this, but it made it clear to me how absurdly intolerant these people are – at .ml, open discourse is actively prevented and that is unacceptable to me.
As a result, I have stopped my financial support for Lemmy development – despite FOSS, I simply cannot support people whose stated goal is apparently to replace one propaganda machine with another. That is the opposite of what is important to me.
My financial contribution will now go to other projects. I'm very sorry as support for the software development is of course important, but I simply can't trust people who approve of such a restrictive approach to social media.
Sad but true. I see it the same way: .ml seems to me to cause a lot of harm. The arbitrary censorship there - imo there's no other way to describe it - is damaging the reputation of the Fediverse as an open approach to social media, which is why I think it's indeed time for decent instances to defederate.
I mean, especially for new users who are unfamiliar with the decentralized nature of the Fediverse, it's an unpleasant experience when they post something completely legitimate in one of the (seemingly) large .ml comms and then get censored by one of their deluded mods.
This can easily give the completely wrong impression that Lemmy would be something like Truth Social just on the other side of the political spectrum, which .ml actually is – and in my opinion, this needs to be prevented at all costs.
