People hate blockchains because they're tired of the spam from cryptobros who have done nothing to create anything actually useful.
Bitcoin is destroying the environment while providing no real decentralization since most people don't run their own clients. Other shitcoins are either outright scams or vulnerable to client forks like when Vitaly stole 150 million dollars.
After not actually solving currency, cryptobros moved to selling random pixels and now want to make the web an even worse place.
Not everyone wants that.

You'd be surprised, but not everyone is trying to run a get-rich-quick scheme.
