One can not simply steal the kind of knowledge and expertise so developed. The momentum developed by one technical group cannot be simply transplanted into a competitor, it transcends documentation.

When you have competitors, people who live to fight others, that’s when you get imitators. The speed at which they can take in new information, which is affected by how much work they are doing and how much time they have to copy it, will drastically effect this.
