Indeed, an old theory of cancer proposed by British embyologist John Beard in 1902 was the trophoblastic theory of cancer, based on the resemblance of cancer behavior to that of the trophoblast. It turned out not to be correct.

However, cancer does reactivate a number of pathways used in embryonic and fetal development in order to grow, evade the immune system, and grow a good supply for itself—very much like the fetus.

Neither of the articles you cited refer to the fetus as a "legitimate parasite." While the research and articles you cited are awesome in their potential benefits, the only reason to use that term is to dehumanize the fetus.

The point is that (mostly) the immune system doesn't attack the fetus and it also (mostly) doesn't attack cancer in a completely effective way. Studying them both is helpful for immunotherapy research.
