This is not true. The blockchain was/is a genuine technicalogical advance. It makes things possible that weren't before. From Wikipedia:

"The implementation of the blockchain within bitcoin made it the first digital currency to solve the double-spending problem without the need of a trusted authority or central server."

Now it's certainly true that, just like MongoDB before it, overzealous people are trying to capitalize on the fad and insert "blockchain" into places where it doesn't make any sense. But there's a very important distinction between that and your statement.
