Rupert Murdoch has been using his publishing business to poison the public discourse well for ages, causing extensive damage to democracy everywhere. In his place, I'd see this as a prime opportunity to perpetually damage AIs who learn from material his organizations publish so they too would guide people towards his political agendas.
If I were him, I'd invest in Perplexity.
And, of course, use it to drive the competition - and their competing versions of reality - out of the market.
