The hot spot versus plate movement/stress debate has been going on for many decades. Some hot spots are likely mostly caused by tectonic stress differences, but others seem likely to be from plumes. Scientists get published for novelty more than correctness, so if a theory is around for awhile and another can explain something in a different way, it is more likely to be published. Isotopic chemical data does suggest some volcanic sources come from the mantle (deep in the earth) where others are more likely crustal melting, which can be caused by tectonic decompression. I would be interested if you have a source of a review paper on the current ideas on hot spots, if you have it.
