eBay playing big brother, no more negative feedback option

I am not exactly sure how I feel about the news that eBay is going to ban sellers from leaving negative comments about buyers? You see I got a really negative comment once. I left feedback saying that I thought the postage was excessive and not clear, but that the product was fine. The seller came back with something along the lines of ‘terrible buyer, never do business with them’, and of course followed this up with a email offering to jointly remove our negative comments. I declined as I reckoned that anyone reading all the other positive comments wouldn’t be put off and I wasn’t going to be bullied.
