This is often repeated anti-WL propaganda that isn't true. There is a vast amount of effort that goes into censoring leaks and it's by far the most time consuming part of the process. They spend literally months on it. Just because they chose not to censor something that you would have preferred for them to censor doesn't mean a tremendous amount of time and thought didn't go into that decision.

This is also not true. Why would WL refuse to publish something if the source could go to literally thousands of other journalists? It wouldn't serve them at all to refuse.
