The Internet was seen as a great liberator when the small guy could compete against the big corporations. But fast forward 20 years have we lost the benefits of the net with the way it is now dominated by a few large companies? From being a liberator it has become controlling. Will we see the same happen for blockchain where initially we can see it as a great disruptor and disinter-mediator only to become something that over time becomes less free and more controlling?
The Internet is still liberating to many people, they can get info and establish connection that are not possible in real world. The Internet is very far from becoming the Big Brother, except maybe for countries like China. It's true though that because of some big corporations and hugely popular platforms like Facebook and Google the Internet becomes a new danger in our lives and can be used against us.
There are some parallels that can be drawn with blockchain, but also there are differences. Blockchain might be used to tighten the control over population if it will make banking ledgers and other centralized databases somehow more efficient, but blockchain also has way less potential than the Internet to revolutionize anything, so in the end it might be not a big deal at all. And since Bitcoin is already very successful, the benefits of blockchain for freedom will likely be bigger than its harm.
