Yeah Kobe's definitely weren't selling like that. There were hoopers that wore them, but overall they could always be found everywhere...especially at HoHs stores - every colorway, eventually to end up at outlets.
As for Vanessa, what did she think was gonna happen? The sneakers/colorway she designed was work for hire. It belongs to Nike, so eventually they are gonna get dropped. There's also the possibility that someone would have them before you, being that someone could take them straight off the production line, before Nike could officially ship to you. Nike doesn't care about Kobe's legacy, they're a company, and they're gonna focus on their bottom line, including profiting off of his death.
Hell, they'll still release Kobe's in the future under Nike Zoom "Prototype" or whatever they'll be called. See Chuck & Webber
