Don't be too harsh my friend and look at it this way - Most of them are legit projects. Reason for these kind of reviews is one and one only:

If a person coming from SME with 12 years in Telco ( CEO of APAsia.tech - Hive account@britcoins ) can't wrap his head around the blockchain offer and explanation for business/enterprise use... Yeah, they need to polish up.
