Fees - They just keep finding clever ways to raise them every year. I started selling on there back in 2007 and since then I can recall several fee raises. Fees on shipping, forced usage of Paypal which allows double fee dipping, 10% fees for all categories, removal of the Powerseller discounts which used to give 5%, 10%, or 15% depending on your level. The "Top Rated Seller" as a replacement with much higher requirements to achieve in order to lower the overall number of people eligible for fee discounts. Another thing with the fees is that rather than intercepting the payment and collecting the fee when the buyer actually pays, eBay charges you the fee instantly when the item sells regardless of whether the buyer pays or not. So if the buyer decides not to pay then you have to wait a whole 8 days before you can get your Final Value Fee credited back. By front loading these fees, eBay gets to collect even more revenue from fees upfront. There's no reason why they can't collect the fee at the time of the payment like EVERY other venue seeing as how they actually own Paypal.
Buyer Protection - Being that everyone is forced to use Paypal, there's really no reason for the eBay Buyer Protection as Paypal already has it built in. The way this program is advertised and marketed so heavily to buyers actually encourages the dishonest buyers out there to scam sellers. They know that with certain items, just slightly complaining about any little detail could result in a partial refund, a total refund, and sometimes not even having to return the item. There is also no negative feedback or type of system in place to warn sellers about bad buyers. The extension of the return period to 180 days is just absurd. There's no item that I can think of where such a long return period is justified. No retailer allows returns for that long. A buyer could go on eBay and buy his textbooks for a college semester, use them, and then return all of them after the semester is over.
eBay doesn't feel like that open marketplace where you can go and clear out some unwanted things in your garage anymore and make a few dollars. It's way too bureaucratic and geared towards drop shippers and big companies now. The hobbyist seller is pressed by their "selling standards" and requirements. It's like they want to be Amazon instead of being what made eBay, eBay in the first place.
But due to the sheer volume users on eBay, there's really no better place to unload random things from your house. So for that reason they can continue to raise fees and do whatever they want.
