Didn't know this.
Google-fu:
Why Is Disney+ Delayed In Europe? | What's On Disney Plus
Seems like the Europe versions will need to have less content in order to comply, otherwise Disney would need 1000s of shows/movies in order to offset their massive collection(s).
It did mention movies "partially filmed in the EU". So I wonder how much can "count" toward the %.
This rule sounds more like a virtual "wall" to keep culture/business within borders. Kinda funny considering how these countries are all involved in the global agenda. Personally the rule sounds like a great idea although shitty for consumers/media companies.
