The notion of “class” is heavily overloaded. Here I am referring to class as a socioeconomic identity derived from income, educational attainment, and occupation, following Kouaho and Epstein [37] . As a finer granule of class I will focus on profession (i.e., occupation), as members of a profession are typically (though not always) also homogeneous with respect to income and educational attainment.

Slur: comparing someone’s work which is confirmed not to be using AI with AI-generated work, as a means of critique or negative reflection on that person’s abilities.

The author is clearly cherry picking definitions of "class" and "slur" in order to call that behaviour "classist slur" - because the later is negatively charged. Pfffft.
