They either skewed the numbers or the popularity was quickly draining when even kids want something exciting than “ponies doing whatever”.
The other day in sickness I posted the “Inevitability Effect”, which applies here. TYT got more views (which is the only thing tracked on kids videos for legal reasons as it’s the only thing that doesn’t require an account) and fewer downvotes (it presumably didn’t get any because of COPPA) than MYM (which is on Netflix; which is behind a paywall, AFAIK locks views per account, and does allow for user reviews etc).
