Sellers can no longer give buyers negative feedback

Ebay have made a big big mistake. It feels that all sellers are going to be held to ransom by buyers. This really worries me as I get so many 0 feedback or new ebayers who do not understand ebay and are too quick to leave a negative. I feel like we will be grovelling to every buyer to avoid bad feedback. But what about all the buyers who never pay, or pay late or cheques bounce ? Also if a buyer leaves good feedback is there an incentive for lazy sellers to give feedback, especially if they are new sellers. Ebay should be a two way fair system. I read recently that google maybe setting up their own ebay style site. I think many sellers would decamp to a fairer system. I would.
