Do you really think Zuckerberg is personally concerned with the "Rare disease - UK" Facebook group to the point where he personally will wipe it out arbitrarily? What if this group was in Reddit and all of a sudden the mod, on a whim, locked all the threads? What if this group met in the local community center and the building owner, on a whim, decided to sell the building to someone who didn't want such groups to meet there? Someone has to be in charge of a "single communication network". If your community owes its existence to it, they are at their whim, and in a way, that's the cost of doing business. This isn't unique to Facebook or Mark Zuckerberg. If the community is strong, they can find a way to overcome such whims.
