I think eBay made a fundamental strategic decision a while back. They no longer WANT to be "the world's garage sale", where a lot of individual sellers sell small quantities of stuff. They want to concentrate on larger volume sellers and business arrangements with corporate sellers. They want to transform themselves from a giant flea market into a shopping mall. They want to be more like Amazon than like the old eBay. In the process, they don't care if they pi$$ off all the small sellers and drive them (us) away. In fact, it is exactly what they are hoping will happen. So go ahead and complain... it won't do any good.
Very, very sad.
