That's the sellers' prerogative. If you don't like the way Ebay does business, don't do business with them.
As far as things like cutting pay, I had to give across-the-board pay cuts to all of our employees when the economy went south a few years ago. I had numerous people come into my office and thank me for doing it, since it saved quite a few jobs. A ten percent cut is better than unemployment. Sometimes you have to step outside your inherent hatred of corporations to understand why they do what they do. BTW, when we gave pay cuts, the company's owners took the first and deepest cuts.
