Not sure why people complain about ebay. If you don't like it then don't list/purchase there. At the end of the day, whoever started up ebay did so to earn money, pure and simple...and as
much money as possible.
There can be no doubt that the introduction of these latest measures by ebay is an attempt to squeeze yet more money from those that interact with the site. Are ebay's fees overly high? Possibly, though I have heard it said that you would pay similar percentages in a real auction, and the latter obviously does not have the worldwide exposure that ebay does, Sotheby's excepted!
You can consider ebay's fees unethical/unfair all you like, but implementing measures that increase profit is nothing less than the correct business decision.
