That said, the reason for removal provided by Google seems to be nonsensical ("abusive content somewhere on Matrix", really?), so mediation should be effective here. This particular reason easily applies to an application like Google Chrome, and EU regulation 2019/1150 requires differential treatment to be documented, which I don't think it is in this case.
Yes, any Element user can report abusive or offensive content to admin of the Matrix server they connect to, and admin can remove the content locally and/or block remote Matrix servers from which the content originates. At their discretion.
But it's on by default, just like Reddit apps are required to have NSFW filters on by default.
I dunno if it's possible to do this kind of filter on Matrix.
That said, if they go with this argument, the precedent would have to apply to all other unfiltered, federated messaging clients, including those for IRC and email.
