The difference is that the Eye of Azshara and other stuff got many people screaming "fake" right from the start and this one, as it seems, begun to convince some of the people who are usually skeptical about such things.
Besides, there is no objective way to prove EoA is a fake. It's just something that someone wrote, you might argue with him but unless Blizzard says it's fake, it's all a matter whether you decide to believe it. I mean, how else would you prove it wrong? There's no hidden data to find, photoshops to be discovered, etc.
I don't know if it's fake, or not but if it was generated in the office, like the OP says, and not with the web site, the metadata could be MS Word.
Here in the office I can manually generate a PDF from our system, and it opens MS Word in the background and generates the PDF.
Eye of Azshara is considered fake because it no longer exists on any trademark database as of right now.
No matter where you go or where you look, you won't find "Eye of Azshara" being registered under Blizzard, or even filed and being processed. It's been completely removed, with the only sign of it ever existing being a broken archived page in the Benelux database. It was only ever briefly on the Benelux database before being removed, never appearing on any other databases.
It's currently in the same state as any other fake leak out there. It's a name people have clung to, but it doesn't tangibly exist.
Heh, just last week I was saying Blizz should mimic FFXIV a bit by having players join a secret group working outside the Horde/Alliance that isn't involved in their politics and battles and was suggesting a reformed Council of Tirisfal Glades.
Lets them drive the story with the players working on their own for Azeroth but intertwining into Alliance/Horde activities at times. I feel like the players have become too much "military members of the Alliance/Horde" and not "adventurers" for a while.
Even if ignoring the 1996 date, BLZ register stuff all the time. Most of it never used.
