Denial of Qualia has long been an outlier position in the philosophy of mind, so this is not altogether surprising. (This is saying nothing, of course, about whether it is true or not.)
I don’t know that I’d call it that much of an outlier position. Compatibilists, functionalists, and plenty of physicalists in general would deny that qualia exist or that they’re a well-defined notion.
