Etiquette Question RE young crochet designers

Hello, I was an adult when highspeed internet came out so don't tie me to a post and set me on fire please, but I was wondering what the etiquette is when you see a young designer who seems to be claiming that they invented a crochet stitch, and in fact are making it their entire identity, including for sales, when your grandma was using the stitch on face scrubbies in 1952? Like they're putting ™️ on the stitch name and everything, and, is it like broccoli in the teeth where you just agonize about whether or not the person wants to be told, then quietly go home and pretend you didn't see anything?
