You do know people can launch a crowdfunding project that is decentralized, They don't need an ICO or blockchain, just a website.
But there is a reason people don't do that, something to do with the value centralized platforms provide.
Plus I'm not entirely sure anyone should trust smart contracts to actually perform such a function, next thing you know someone other than the project created takes all the funds pursuant to the smart contract, but hey that's the beauty of a smart contract it's infallible, so what ever it does it was intended to do, be damned with what people thought and understood it would do.
