Without decentralization you wouldn't have "A few Telco's" you would have 1 global telco. The most hardcore form of decentralization usually means that there is no centralization ontop of the decentralize medium. I think this is in general unlikely. People are lazy and tend to congregate together and therefore there will always be some form of centralization. Not everyone wants to think about the implementation details and just wants stuff to work without caring how. Whats important with decentralization is choice and future proofing. When one company dies or becomes untrustworthy you can jump onto a different one. Proof of Work is one implementation but not the only one, there are many more efficient versions now. You might as well complain about Dial-up saying internet is a waste and will never amount to anything because the phone line is always tied up....
