Possibly because it's a billionaires plaything and they're constantly trying to shift the needle in their favour with their abuse of media ownership? These aren't 'just' private companies.
It doesn't matter how you slice the salami of their private ownership, there's no agreement between you and them like there is for say the BBC where the public have a right to shoot down mongering and substantial bias.
So it's completely up to you if you care. And if someone else does care about these grubby royal gossip stories it's not really your problem.
