I find this arguing over labels more and more as I browse online, and it is sooo exhausting. I have noticed so many instances of arguing and discourse where both sides have similar ideals and want the same things, but argue with each other over stereotypes of labels on the other side, and point to the faults of the vocal rabid minority on the other side as if to prove a point. Sigh.
I’m on the other side of your opinion - I like that phrase. “Content” can mean art, audio/visual media, writings, etc. - basically anything that we consume.
IMO, Professional creative like artists/writers/performers are all content creators but not not all content creators are professional creatives.
In this day and age, everyone creates music, comedy, videos, skits. Some work a job primarily but create media or rabbitholes that can be scoured through.
I think “content creator” is a nice catch-all term for personalities that do a lot of stuff that can be casually consumed for entertainment or discourse, especially because it stops limiting said people to one occupation like “musician” or “author”, while also preserving the seriousness of those occupations.
