I think ebay kinda got their vision out of sorts. As a paying seller on ebay, I (we) are the real customer!
The buyer's on ebay are our (the seller's) customer's.
It's all about customer service, and had they provided the service, then they would have been well served in turn.
Ebay can preach all day about how we the seller's must adhere to all kind's of standards, yet refuse to maintain any on their part.
Instead, they have decided to stick it to us, their customer's, and in this, we the customer's have found other markets out of necessity.
Simple economics vs greed. Greed always loses out in the end, and the market will find a point of equilibrium.
