I don’t think it can, it’s a flagship because it’s the first instance, being run by the main devs as a demonstration of Lemmy’s capabilities so it’s always on the latest beta version at least.

But, they could just stop using it as a tool to further their own political stances and have it actually be a “generalist” instance. For that though, they’d have to give up being the admins of it, which they’ll probably never do.

It is of concern yes, but maybe if the wider Lemmy-verse defeded from them, like they did Hex and Grad, it would at least be easier to say that their views are not shared by any of us to any newcomers/outsiders by being able to point to a clear and visible action like defederation.
