Yes. I'm not sure the author understood the subject. There is plenty of evidence that Neanderthals made and wore jewelry. The study was about Châtelperronian industry in particular not jewelry in general.
I don't think we can really blame the Neanderthals for that. Killing animals was likely viewed differently due to its necessity then. Plus, a lot of the protests now are due to industrial practices and sustainability issues that didn't exist then.
