Thanks for these questions! For the demo we rely on blockchain tech for AMPs, while we rely on SpecialK for content distribution. Blockchain certainly won't scale for content distribution. On the master branch in the repo all the blockchain calls have been backed out to be replaced by the appropriate blockchain tech. If the Casper work goes as planned we may end up with our own blockchain tech, or with a branch of Ethereum. That remains to be seen. Regarding your other question, authorization depends on a private key that is under your control. Let's think about the larger issue you raise, though. If you use an AMZN node that we're hosting, the system is decentralized only in name, regardless of where the key goes. We are free to shut down the node at any time. After all, we're paying the AMZN bill. For the decentralization to begin to be meaningful we'll have to have many people standing up nodes.

Regarding your other comment about building a better Synereo, i would love to see your better Synereo! i think many people on the planet would. Can you send a link to your repo for the code? What's the programming model for building distributed protocols? What's your tech stack based on? What's your transaction model? How do you handle content distribution versus currency? These are just a few of the many hard questions that have to be addressed and do get addressed in a due diligence interchange with serious investors. If you have good answers, we would love to hear them! This is a very big space, with room for everyone to engage and contribute. All ideas are welcome!
