Some people will be fanboys of anything they spend a meaningful part of their day with, because (a) it makes them feel good about themselves, and (b) they don't know any better. They're still in the larval hacker stage where they still have binary opinions about everything, because they don't yet have the technical depth to have more nuanced and informed opinions about this stuff.

If they can convince themselves that the few things they know really well are the only things that are important to know, then maybe they don't feel bad about all of the things that they're just starting to realize that they don't know. That's my interpretation at least.
