I don't have a horse in the race, but I'll just play devil's advocate here...

Two things...

1) It's a proven fact that peoples' memories are terrible. Not only has this been shown by many on the Classic WoW sub-forum (on Blizzard's site), but eyewitness testimony (normally from an event that took place much earlier than 15 years ago), has been repeatedly shown as an unreliable form of evidence, in a court of law.
2) We're playing a version from September 2006, and in those 19 months from what you remember in December 2004, spawn rates related to Devilsaurs could've changed in that time.

Blizzard can say whatever they want about "the implications of the economy". It's nonsense. If you have 1 zone, producing say, 40 devilsaur leather a day, versus how every many layers exist, say 20 (I have no idea how many), guess what, roughly 20x as much devilsaur leather is coming out of Ungoro day to day, than did 15 years ago.
To just quote Blizzard again (from the same post up above):

All realms have a single-digit number of layers. Most of them have a low single-digit number.
Why would they even say that if it was any other number? Is this all a conspiracy cover-up by Blizzard, or are people not actually abusing these things like some others believe?

Could an alternative explanation be that because there are currently more people on these Classic realms than any Vanilla realm had ever seen, this causes an increased spawn rate, which, in turn, increases the amount of materials on the auction house?
