As far as I can tell, this is awkwardly worded.
My first reading made me think that Rumble has a fraud scheme -- in the same way that the old Twitter did -- which supported censorship.
But I think the author here is actually trying to say that Chris Pavlovski of Rumble is teaming up with Elon Musk of X to make sure that both X and Rumble can fight the censorship fraud that many social media platforms have adopted.
My reading is that these entities are weilding their perverse algorhyms on X and Rumble, and thus need suing.
