1, That's disrespecting the person who put in so much effort in design and engineering to develop the product. That's intellectual properties
2, Buying knock off is encouraging these illegal activities. Sooner or later, no one is going to cmake good products
3, Hey, if you can't afford it, don't buy it. Why pretend you are there when you are not? You can cheat the others, but can't cheat yourself.
As long as you know what you are buying, copy cats are ok, not every one needs the top notch products. I agree that most of the Taiwanese brands are good enough for Hong Kong road environment.
Be frank, I can't afford 10k for a wheel, but fake ones(冒牌貨), for me just no way
