I totally agree. Based on the evidence around 2014, I thought this debate was over. The new findings in this article show nothing new to prove 'reptilian'. They just seem to still be calling them reptilian-mammals.
In fact, I actually found one of those old articles with a pretty solid reply that it is mammal: “For decades, scientists have been debating whether the extinct group, called Haramiyida, belongs within or outside of Mammalia,” said co-author Jin Meng, a curator in the Museum’s Division of Paleontology. “Previously, everything we knew about these animals was based on fragmented jaws and isolated teeth. But the new specimens we discovered are extremely well preserved. And based on these fossils, we now have a good idea of what these animals really looked like, which confirms that they are, indeed, mammals.”

In fact, the trend is to call the ancestors of the mammals, and their entire side of amniote family tree, “synapsids” instead of “reptiles.”
