"Street smart" would mean having the common sense necessary to survive in the world. When you consider that professional LP'ers essentially are allowed to make money based on the good graces of developers and publishers, "street smart" also means having the basic intelligence to not be an antagonistic, egotistical asshole to said people who allow you to collect a paycheck.
Considering how much Phil has publicly talked shit about developers and publishers in such an aggressive way while at the same time making money via playing games by these people, this was bound to happen once somebody got tired of the hypocrisy. No one should ever be barred from being critical of the flaws in a product or work of art, but calling the creators profane names ("piece of shit," "fucking assholes," "cocksuckers," etc.) smacks of immaturity more than anything else. Other content creators do this in more tasteful and respectful ways, while still making their point clear about what they find lacking or flawed. This may be a case of Atlus exercising their right to choose who gets to make money off their property. As publishers of the product, they may well have absolute power to choose whether or not specific individuals can profit off of streaming their game. If all of this is due to their belief that Phil had been obscene in his method of conveying his opinion, as opposed to the opinion itself, I could see this as being an inevitability. I would have pegged well-known Phil nemesis Hideo Kojima to be the one who did something like this first, but I suppose the clusterfuck at Konami meant someone else would have to pick up the torch.
