Of course. Why would you expect anything but? Pride is actually a very good driver of change if you ask me because people often do their best work when they are proud of what they are building.
Perhaps ego is a better term. Concretely, why migrate hotmail from unix to Windows except due to ego? The NPV has to be negative here.
Makes sense to me. After all, businesses are run by humans, who have egos to satisfy.
Engineers might take pride in their work, but on this level in a big organization, I rather suspect turf wars as motivation.
