I endorse! Additionally, as a Jamaican and a citizen of the marginalized Global South, I take strong exception to the racist trope that success is measured exclusively by the Global North. As you said, Marley had immeasurable influence in Afrika, but also in Asia and Latin America. When watching a news report on the 1990s liberation struggle in East Timor and a wall with the image of Bob Marley shows up, you begin to understand his influence on that revolutionary part that white supremacy has worked hard to downpress, to use Rastafari vernacular. East Timor rebels stated that singing Get up! Stand up in the jungle was what motivated and sustained the struggle.
I should say too that part of the lack of impact on the African-Americans audience was that black music was equally powerful as reggae, so there was cultural resistance. Ironically, black America succumbing to foibles of divide and rule that Marley sang about as he admonished the unification of all Afrikans, in Africa Unite.
I'm compelled to mention also that what seems like an attempt to place Marley within that argument of opposing the inequities inherent in the capitalist/Babylon system, then exploiting/benefiting from it through ticket sales, is oblivious to the fact that much of Marley's earnings went back into the poor in Jamaica --- sending children to school, feeding families. More importantly, the author is ignorant or fails to mention that in 1980, when Zimbabwe got independence, the newly independent state invited him to perform. Unfortunately, they had not the capital. Marley on hearing financed the whole visit and performance out of his own pocket. Not many know this.
