Since this isn't gaming-related news, I'm guessing Nintendo also owns a newspaper in the Warioverse. They've owned a TV channel in the real world... maybe a newspaper was their dream?
Well Wario is typically the one to read newspapers while being a couch potato, no matter where they come from. I almost see this as a potential joke because Wario tends to believe obscure things he reads from the internet and television newspaper. Then again this is just the Wario universe. Nintendo is probably the business god in the Wario universe.
