Well, yeah, it's the 21st century. The CPC can only be commended for putting an end to this form of cultural appropriation.
Had you actually watched the video in the second link, you would've realized that that rapper himself was very critical of mainstream rap for the same reasons that @Grumbler mentioned. Ironically, the two dudes in this thread who have listened to more hip hop than all of you are in fact telling you that it's not a big deal. Interestingly, none of you actually care about hip hop, yet all of a sudden when the CPC is coming out critical of some elements of it, ya all of jump up in your chairs.
