I can't speak to the WSJ, and perhaps it's a good example of the owner not meddling, but using Rupert Murdoch as an example of someone who doesn't meddle in their media empire invites a lot of questions.

Rupert Murdoch's influence is a very hot topic in Australia, with 2 former prime ministers from opposite sides teaming up to try to push a royal commission into his media monopoly, and in particular his influence on elections. Some of the commission is directed at the actions of his properties, but a lot of it is directed at his specific meddling as an individual. There have been many claims of directives and squashed stories coming straight from the top, whether that's from him or Lachlan Murdoch.
