I don't have a plan or agenda. I think it raises interesting issues about the Fediverse - there is a kind of selection effect in who joins the Fediverse, which I think in some ways can be good (e.g. access to political opinions that aren't taken seriously elsewhere), but I also think as a community we should be wary of its potential downsides.
I wasn't calling for censorship of conspiracy theories. It annoys me that they are proliferating, but I wouldn't call for their censorship. But if the situation got super bad (and it is far from super bad at the moment!), I'd probably seek somewhere else to discuss stuff online.
I did mean itch.io, but that's alright - the ambiguity was my fault and I'm not completely set on itch.io.
