I think the distaste for the word influencer is because it assumes influencing is the thing, where it is actually the output.
Marques Brownlee is… a reviewer, who also makes money by doing sponsored spots.
Mr Beast is really a director/producer/videomaker and makes interesting and fun videos, and “influences” by using his name to market burgers to make some extra money, but he does that because he is a video maker not because he is an “influencer”.
While teens say they want to be influencers growing up, I think it would be more healthy for them to think about what they will do to become influential first. It’s like saying you want to be famous without deciding if you want to be a musician, actor or famous scientist - fame is the output not the title and shouldn’t usually be the goal.
