My guess though is that it's all just a show. I really doubt that other companies are incapable of producing devices like that. They just don't launch them because they're probably not viable one way or another (quality control, demand, ROI, etc). And yeah they're definitely stealing. Huawei has been caught pretty blatantly doing so.
