Why don't many black people like Lupe Fiasco?

Is it because they can't comprehend his lyrics? Lil' Wayne is only good because the majority of the black population understand his 3rd grade metaphors. Jay Z use to be great back in the early 2000s, but like NaS said, he traded his soul for riches. Jay Z even said he "dumbed" himself so he could be more popular and people could understand him..
