That doesn't really address GP's comments directly. It's never a good career move to trash someone publicly, and it's not fair to call out anonymous sources for protecting themselves from a backlash.
As for your complaint, it's certainly true that almost any angle can be supported by a single source. Good journalists can solve this by finding other sources before publishing or verifying in other ways (viewing email histories, for example).
