One of best features of TikTok is how easy it is to create your own content. You don't even have to think about it: just duplicate what another video is doing with exactly the same moves and exactly the same music. In that sense, it's definitely social media, since almost everyone on that platform is also a creator.

I think it's worth re-evaluating the use of the word 'creator' if people are uploading a video that's 90% copy/paste of something else.

At best its grist for the content mill. Cheap animal feed to fatten the livestock and attract the eye of advertisers.
