A properly decentralized blockchain isn't a third party in the traditional sense, a human or organization that is bound to follow its agreements until it doesn't feel like it anymore. It's an algorithm incarnated.

That said, its initial and continued existence is dependent on economics. Who will market a service that they don't stand to profit from? Who will drive large organizations to invest in infrastructure that doesn't improve their profits? Either no one will, or it will be adulterated in the process. Sadly the community spirit that drove a lot of early internet development seems to be lost.
