Before reading the article and before seeing your comment, I was chatting with my partner about the 737 Max, advising her to be wary. And lo and behold... You are definitely not alone in this.

However, and to play a bit devil's advocate, China has a reputation as being a place that does not care about the value of human life, and the current climate is charged with USA advising people to ban Huawei's hardware, so this could have ulterior motives. If it was France banning them, nobody would bat an eye.

Political or not, in my eyes it is definitely the right move.
