I read that the progress pride flag is copyrighted and some people (or a single person) may be profiting from it.
Several sources seemed coherent with this. That’s why I try to keep away from it. And also it seems be mostly used in USA anyway, I haven’t seen it much around Europe.
Chinese is not a global language. And it’s not likely to be in the future. It’s not the raw number of speakers what makes a global language but the number of non-native speakers.
That being said.
In my country, Spain, it is not taught at any level as mandatory, and not even as an option. Of you want to study chinese you have to go to do as an extracurricular thing.
