Who isn't greedy? I'll be the first to admit it, I am greedy. If I buy a product, I want full access to it. If I pay $5 for an all-you-can-eat buffet, I want to eat all I can. The point is this: Multi-Billion dollar companies do not just set a service and make promises out of the blue. Hundreds of thousands, if not millions, go into market research.
Sure, if you go open a pizza parlor and offer unlimited pizza for a set price each day you are going to go bust. But if you do the research first and crunch the numbers, you will be able to offer the service in a manner that will make you money. So don't think for a second these big companies do anything without knowing what they are getting into and a good idea of the outcome.
Rest assured that they are not there to help you. In the end the only concern of the company is the bottom line. ($$$) Don't get me wrong, no one can offer a service and not make money. But there should be limits. For example:
Go to Best Buy or another store like it. Buy a Micro SD 2GB memory card. It will cost you about $45. Go to newegg.com and you can buy the same thing WITH a USB Card reader for $15. Both companies are making money off it. Where is the greed here?
So in summary, yes Users are certainly greedy. But no more so than the corperation who provide the service. Perhaps some users need to pay more attention to the fine print. Maybe the corperations should make the fine print larger and easier to find. Bottom Line--- Everyone is GREEDY, User and Corperation alike.
