TBF content is generally better than it was 15 years ago even for babies. I don't blame em...
My impression was that a lot of the content was effectively "attention slop", bright colors and noises, often with very little sense to them, or just variations of the same rhymes a 90's baby would've been raised on.
A lot of it seemed to cross over from just being stimulating to being overstimulating.
As Weller said, that's entertainment. Saying something's slop is like saying it's trash, ie something you don't like.
pure speculation, and dare I say, hysteria
