I’ve read Rand. The author of this article was very generous referring to Rand as a “philosopher.” She was a philosopher in the same way Jim Jones was. She was a cultist. And even decades after death, she still has a following.
BTW—I’ve read nearly every word Rand ever wrote. The only thing that impresses me is she wrote 2 thousand page novels in her 2nd language. Her ideas were poison, but I can’t fault her determination to write. :-)
