My personal reason is that having been an ebay user for a long time without ever having sold something, the gallery plus being a feature that is not optionable means I am refuse from being able to sell an item. Mildly put, it hamstrings the fucntion of it as an auction for me and now having a bunch things of sell, I am mightily hacked off!
dave, what the OP is referring to is some sellers right now are being refused the ability to list because Gallery Plus is only for experienced sellers, yet they can not opt out of using the gallery plus. My mother in Law is having same problems it is even stopping her from revising existing listings. She has been on the phone to me asking my help to figure out why it is happening.
