People care about it beacuse it allows them to put an asterisk to achivements and make their faves look better and compare artists on a more level playing field instead of comparing a 2 year group with a 15 year old group etc..
X is the best selling girlgroup* (4th gen)
Y is the fastest artist to reach 2m likes* (4th gen boygroup)
etc etc..
its kinda dumb but it is what it is and i dont think it will ever go away.
