I’m not sure how that really is an argument against my point. Thousands of scripts exist, and in the process of them getting made, the funders and producers have influence on the content.
The idea that fully-written scripts are just made without any input or pushback from the funders/producers is not how the film industry works.
No, that's exactly how the Industry (also) works. There are different styles of projects, but scripts being finished before any money flows in, is pretty common. And at those point changes are usually small. And usually they also don't plan ahead to become some global hit.
But the point is that Netflix specifically buys productions from different countries, to cater to the fans of those cultures. If they wanted to have a US-ified script, they wouldn't need to go to such lengths, they could just hire some us-asian writer to get another ethnic US-series.
I think they're making a <valid> claim that funding creates a bias. Netflix funding squid game created a bias to rewrite a potentially-done script for US audiences.
Netflix wants subscribers in Korea so they have every motivation to create content that Korean people want to watch. If Americans like it as well that is just a bonus.
