I'm not seeing how this is unfair. Facebook is a business and the companies which set up fan pages are not typically charities (and so what if they were).
Facebook has a level of PR software as service which is free. They have another which is premium. If a company wants to spam their "fans," they have to pay.
If a business wants to have a high level of control over communications with it's fans, customers, likers, or whatever they are called, there's no free lunch. Either pay a third party (e.g. Facebook) or invest the hard work.
Absolutely. This isn't a change from 100% of fans seeing a post to 0% of fans seeing a post, either. Even when Facebook just chronology to organize the Newsfeed, plenty of people would miss a post just because they weren't at the computer at the time. This is just a different, maybe better, maybe worse, way of organizing the Newsfeed.
