Anybody that thinks they “own” any portion of what they do or have a say in anything on a website other than their own is deluded. Just because you use a website constantly, buy things, have friends there or feel welcome doesn’t mean it’s yours. It belongs to the website creator and they have to answer to the EULA (or whatever the big boys have) of whoever is serving their site.
Facebook has never had a good track record with privacy or fairness, perceived or otherwise. Someone needs to come up with the Facebook killer. Hopefully something open source. Though I have my doubts the open source crowd could pull together on something of that size and scope.
