Can we say a country is a community? Then many such communities are working really well today still. The biggest problem when a community grows is the partitioning of this community, a successful big community is the one which found a way to union many smaller communities around one idea and make the whole system work together. Your examples are touching only commercial businesses for some reason. Community there is just a hoax to _engage_ you, utilising your prime urges to connect and communicate with people. Commercial business only goal is to get more coverage and cash flow really, so they choose growth strategies to get their service more drug-alike but they can't (and probably don't want to) build a great community pursuing these.
