I'm a cosplayer and I've never heard anything about it other than my gramma being mad that some of my outfits can't be worn with garments. To me cosplay is just an art medium to play with and can teach you many skills in fabrication. I've learned about sculpting, sewing, fiberglass, painting, 3D printing, pattern drafting...just to name a few. It keeps me motivated to learn :)
