Because people is now making ridiculous projects over the blockchain, and they do not even understand why blockchain means, they are just using that word because it has a lot of potential to do marketing.
There are some projects like Sex on the blockchain from a sexshop ico, i do know what has been about that ico, i thought that they rised more than one million dollars from this ridiculous idea.
And there would still be some more projects like this, they are like a plague . But if they are really good projects, then i dont see why they can not develop an idea over the blockchain, it is helping everybody in here at any way.
Not only the blockchain, even majority of the developers don't know about the means of the decentralized itself. A lot of the project that only runs in the one blockchain and then said about that was based on the decentralized thing. This becomes a bes joke right now how the developers lack of knowledge about the crypto definition itself.
