Good article. I think evolution of Internet was, and definitely will be, a permanent cycles of centralizations and decentralizations. Now a pendulum is close to side “C” and blockchain is a “native reaction” to turn it back to “D” side again. But it isn’t the only way to do this. Now we see the dawn of new epoch of web apps. It’s very important now to make techs of web app development, deployment and support REALLY FREE, independent and decentralized. It’s right time to leave GAFA’s dev ghettos.
