I think there may be more to this than is on the forum thread.
Question: who plays the thief? Is it some sweaty nasty guy, or the DM/GM/WE's gf/bf/sexual favours vending machine? My first GM had his girlfriend, who was stunning, as the party thief. They deny the connection, but for some reason by level 7 she had a suit of elven chain, boots of elvenkind, +2 weapons with abilities, and lots of gold, and I had a +2 dagger and no armor. I was the party tank.
The excuse was that, as the thief, she was finding stuff; and that roleplaying that meant not sharing with the party. In 2e the class was named "thief", so who could argue?
EDIT: this is why I mostly GM now.
