Is it controversial to say that mainland Chinese companies (as we're talking about here) commonly steal or clone business plans?
The OP wasn't starting a conversation about business practices, they were attempting to make a witty one-liner by denigrating a group of people and reinforcing a negative stereotype. They were implying that Chinese people don't need to be educated because they do unimportant work.
Imagine if someone had said that it didn't matter if women or blacks cheated in exams because all they did was housework and unskilled labour ? - that's exactly the same as what the OP is doing here.
Or Tencent?
Or Alibaba?
The "copying" that you seem to be referring to, is no different to "normal business" in the US: Apple open a retail store, Microsoft open a retail store (or was it vice versa?) Is that "copying"? or is that "competition"?
Is it only copying when the parties are different races? or more controversially when one party is chinese?
