I think the Facebook example is a terrible example. If that had been their business model since day one, then fine, they can do whatever they want because every new user knows what they're getting. But if they get huge because users are flocking to their site without having to pay anything and dedicating a lot of time to the site, they shouldn't TAKE AWAY features that were previously free. That just seems wrong to me. That was the model they chose and that's part of the reason why they got so big. I don't think very many people created a Facebook account with the idea that they would eventually have to pay for what is currently free. If FB had this business model from day one, I highly doubt they'd be as big as they are now. I think it's up to them to figure out a way to make money while not charging for any CURRENT features. If they want to charge for new features, that's fine; otherwise, it's just a bait-and-switch and they're doing a major diservice to the large user base that made them who they are.
