So basically Spike Lee doesn't do the right thing?
Like him or not, seems he had absolutely nothing to do with any of this.
As the open letter makes very clear - it was bad behaviour on the part of the agency, and Spike most likely didn't know it was going on (and the letter even suggests the agency was actively lying to him about it).
But - Spike is ultimately the one in control of the money-tap the agency is drinking from. While he had "absolutely nothing to do with this", it was no doubt done on his behalf, and he absolutely has the power to fix it. If he says "No, that's not how we do things", then it'll get fixed. (Arguably there are many other people below Spike who could also make that call, but I have some sympathy for the original poster - it would be a great deal of work if it's possible at all, to find out who in the middle management chain of command has sufficient authority to solve this problem and how to contact them directly.)
