Because journalists talking amongst themselves completely fabricated the story.
Obviously there's been some sort of hard evidence if there's this much corroboration between multiple sources. Reporting on and talking about the implications of such a delay is not "bashing". I realize as an AMD proponent you may feel defensive and a bit reactionary at this news but looking at it from an unbiased perspective, it's pretty clear that the delay is real.
You want hard evidence? AMD themselves said it's on track... AnandTech is the ONE website that said it's delayed. Because THEY said it, everyone else has reposted what THEY said... there isn't a group of people doing this, it's just AnandTech...
