>That's exactly the reason I was thinking they may choose to be selective. From what I understand, it's pretty normal for servers to refuse to federate with other servers. I don't know if they do this transitively, but if so, then the Dutch government might find itself forced to choose which side to take.
I'm not clear on what you mean by "forced to choose which side to take."
You (or anyone else) don't have to have an account on that instance. In fact IIUC, the site linked in the submission only has accounts for the Dutch government and elected officials of that government.
Folks other than that can follow individual accounts on the Dutch government instance, but aren't subject to any moderation decisions made by the site. Only those with accounts on that instance would be affected by blocks/bans of specific users or instances.
And even if the Dutch government instance wants to block other instances from their users, there's nothing stopping Dutch government officials (and/or agencies) from creating accounts on other instances.
As such, please explain what you mean by "choosing a side." I'd expect that this site is on the side of The Netherlands, its government and citizens. Isn't that the way it should be for a site like this?
As such, please explain what you mean.
