Can't anyone still share information using the normal internet? You don't need the blockchain in order to set up a website and start sharing information. Few choose to do this because it is more work than using a centralized system. Using Facebook or twitter is much easier to use. What does the blockchain really change? So far, it doesn't seem to be any easier than sharing information the traditional way.
Today no one will find the information you share on your website without centralized search engines. A more decentralized internet could change that. "Blockchain" better named DLT however is not needed for that, but it may push the desire to decentralization. If people can have a "de-central bank account" that no one can delete they maybe start to think that all other online accounts you have should work that way too. No more questionable suspended twitter account and deleted YouTube channels.
