This author needs to get out more. Many corporate IT shops have this attitude. You can argue whether it is good or bad all you want, but it definitely exists.
Note: Technology companies should not have this attitude. But how many companies out there truly are about technology.
Is a grocery store a technology company? Your lawn service? Your local pizza shop? Being startups geeks, we all tend to get tunnel vision. Most companies are not about technology.
Even mine, a large energy company -- Our customers don't give a crap about our technology. They care about what we pull out of the ground and how we pipe it across the country. Our IT work has nothing to do with our actual business. IT work measures it, does accounting, handles "office work", etc. It affects our internal costs and efficiencies. But that isn't our actual business, and our customers don't know and don't care about our IT shop.
