Carbon copying another persons work without putting in a minuscule amount of effort is different from taking a proven business model and rolling it out in a different market. It's not like the Samwers steal the sourcecode and design put a new name on it and call it a day. There have real offices, real engineers, real designers, real marketers. You might think cloning a business model is despicable but there is a real effort involved in executing it. Not to mention that unlike in the case of this article the Samwers don't go into already preoccupied markets but rather aim to tap new ones.
