I kinda see the point though. State management is bundled with frontend development in such a way that even for simple projects it almost seems like necessity for most people.
Don't use things that you are not hundred percent sure you need. Blockchain is a robust solution for high complex state management issues but most people will never end up using it for its full potential. Even if you did there often are alternatives that performs much better for your need.
People will try to bend their projects to meet the blockchain need rather than just use it when you need to use it.
I think it attempts to paint them as overhyped. If the target would be to put down blockchains, the page would simply be a "No". But it's true that we throw blockchains at things that don't need a blockchain.
