content: Your second bit is absolutely correct. A lot of things naturally become centralized. They always have and always will. That's just reality. If Wal-Mart didn't have so many products from so many categories then there would obviously be less one-stop-shopping there and shopping would be less centralized (until a similar place pops up). If Facebook wasn't so widely used then other options would be more viable for people who want to use a social network to communicate with most people they know. Villiages form because its convenient and beneficial for a myriad of reasons to have a centralized location versus individual people/families having to travel some distance. Same for cities and so on up the tree. Companies have owners/boards/etc. to manage business with the benefit of the company in mind. Social groupings of people such as cities have leaders/councils to manage society and enterprise, ideally with the benefit of the populus in mind. Once either type of group starts to have negative effect, the supporting contributors must take action or withdraw contribution to correct such. Complacency is how things go awry and snowball into Facebook, etc. Physically decentralizing data flow and storage can help to minimize potential for its misuse, but centralization will always come and go at every level. Just some thoughts.
