That&#x27;s normal style in mainstream journalism, weird as it is. If you read a lot of sports journalism for example, you&#x27;ll see a ton of articles which are literally just a summarized transcript of a phone call a reporter got from an agent, written as if it&#x27;s just pure factual information that appeared from thin air. At least in those cases it&#x27;s trivial to guess who the source actually is.<p>Again, it <i>is</i> objectively very strange to not even hint at what the source of your information is. But it&#x27;s also standard practice.
