If you paint with such a broad brush that watching anything on a screen is equally bad, that's a backdoor way to justify scrolling through TikTok ragebait videos since "it's all poison anyway".
Edutainment is a spectrum, while you are correct that everyone should understand they can't "learn quantum theory" in a way that can be applied meaningfully by watching videos, sparking intellectual curiosity and learning new topics/areas of interest is a good thing in general. And most edutainment that isn't so flawed/simplistic as to be wrong is better than watching an influencer whose dayjob is churning out weekly content with some alluring hook to grab viewers and mostly just inane lowest common denominator filler around it.
