As far as the listing fees, it's just a money-grab for eBay. There are a ton of low-priced items sold on eBay and they are tired of someone posting the auction at $0.99, getting hardly any listing fees, and then getting a low commission. Now they are saying screw it we'll give them the low listing fees but we're taking a bigger cut.
Yeah, that's ridiculous. I see what they're saying about buyers not giving negative feedback for fear of retaliatory negative feedback, but it's sellers that are the ones harmed by negative feedback, not buyers.
