> Many coders simply do not care about the business or customers part.

These coders may exist, but they are in my experience not that common. Most coders do care about the business or customers part, but think very differently about these aspects than business people, and thus come to very different conclusions how to handle these topics.

In my experience, it's rather exactly these programmers who are often in conflict with business people

- because they care about such topics

- because they come to different conclusions than the business people, and

- because these programmers care so much about these business-related topics, they are very vocal and sometimes confrontative with their opinions.

In other words: coders who barely care about these business-related aspects are often much easier to handle for business-minded people.
