These are far too strong words to conclude that smart valley actually is scam. It's mean to call people small minded just because they believe in a project you consider worthless. This article that you claim to break smart Valley into pieces actually arises questions itself. Some facts in particular requiere double-check.
But I tend to agree with some of the statements. For one, Smart Valley really lack transparency although it lists it among it's primary goals. Another drawback is that they don't make any updates on their progress, ignore the questions. They just leave us feeling that the project was left behind. At the beginning, I was very supportive of the project. Now I'm very disappointed.
