When you look at it from a legal "use it or lose it" and corporate risk perspective it's quite surprising that Disney didn't even sent cease and desists.
Edit: Of course you don't lose the copyright but your ability to litigate someone else's unfair use is a lot weaker when their lawyer can trot out a million examples that you were fine with.
Nobody who loves Disney songs would listen to them while also hearing police officers shouting, etc.
There's no human to appeal to in social media platforms. It's automated, algorithmic enforcement; and when it's wrong (or someone exploits it to be wrong, like this), you're powerless to do anything. It means nothing if you're technically in the legal right: the platforms are risk-averse and don't care about your false positive.
Ahem...
In the UK/EU Let me introduce you to article 22 of the GDPR
The data subject shall have the right not to be subject to a decision based solely on automated processing, including profiling, which produces legal effects concerning him or her or similarly significantly affects him or her.
i.e. If subjected to an algorithm making decisions, you have an automatic right of appeal to a _human_.

You need to adopt a sensible data protection law if you don't want to be exploited.
(In the excerpt you quoted: "legal effects" / or "significantly affects").
Though presumably you would prefer the alternative; that such companies are unrestrained in what they may do and the population at large must simply bend over and grab their ankles with both hands?
This has never once prevented a DMCA notice from being issued, and I'm sure you can guess how easy it is to get a person at YouTube to review your appeal
There was an article on HN that one city's police force, when there were protests going on, took to playing Disney songs from loudspeakers; so that any recording of their interactions would be impossible to publish on any significant internet platform (or at least, the audio would be muted, by IP protection filters).
