An interesting example might be WaPo, with Jeff Bezos literally being the owner of a major publication. Are there any examples of biased/helpful coverage? Curious how much the ownership affects the editorial angle.

That seems to be a slightly disingenuous comparison. For one, Bezos seems to be taking a pretty light touch on Washington Post editorial content, which probably makes sense for him as an owner, since it's probably worth more as a business if it has a solid editorial reputation.
For two, if you're looking to cast aspersions on the editorial influence of owners, you'd maybe want to take a look at who owns the Evening Standard, since that's the paper whose coverage has apparently been put up for sale. It's Alexander Lebedev, billionaire Russian financial/aviation 'oligarch', who was literally a KGB spy in London in the cold war.
But sure, I bet you're right to be concerned about the sinister motivations of a bookseller now he owns a newspaper.
