The WSJ maintains very solid separation between their news division (almost always solid and rigorous, with decent fact checking, their audience of investors wants good info) and their editorial division (intensely ideological and willing to completely disregard basic facts). So it's important when evaluating a WSJ article to know which part of the publication it came from.
WSJ broke the theranos story, I’m not sure what relevance any of these other ambiguous papers you’re vaguely referring to have to do with the current thread.
