Dismissing youtubers for being youtubers reminds me of people who dismiss all animation because "cartoons are for kids" or whatever. When I think of "influencer" I think of an instagram model who pushes products on their followers. "Youtuber" includes many content creators who devote hours into researching, writing, filming, and editing high quality, entertaining, and educational content.

Jenny is on the low end of the spectrum in terms of basically all of those categories (I love her though), but channels like CaptainD, Contrapoints, Philosophy Tube and Folding Ideas create extremely high quality content that (in my opinion) surpasses educational content coming out of any studio.

tl;dr: Dismissing youtube channels as "influencers" is narrow minded and may prevent you from enjoying content you would otherwise find to be of extremely high quality.

To be fair she does actually lightly use the word in this video to describe herself, but only in order to describe how Disney as a company might view her.
