I have no idea why people put word blockchain in everything, it looks like blockchain is a magic word that's used instead of Abracadabra, I wouldn't even be surprised if magicians say Blockchain while doing tricks. I think that increase mostly comes from former Soviet Republics because in these countries, a lot of people don't had access on PC and internet, there was DSL in most of these countries for a long time and we can say that fiber is new for them.
Also in some countries internet is expensive but at the same time there is a huge bandwidth usage because of pirate websites (multiple upload of different movies, games and etc for each website).
"Blockchain" and "crypto" is this century's "radioactive". They've got radioactive toothpaste, we've got blockchain toothbrush. (Yes, look those two up, they're real).
Though I think blockchain can be used to distribute information (I always think of it as sort of a torrent but each user don't need the entire file to start seeding), I don't think we'd be using it as a replacement for the internet any time soon. We put ALOT of personal things on the internet, do we really want those files spread out to everyone?
