I was on the both sides of the spectrum: from everythig custom-built to everything is a third-party dependency. I guess you managed to find the balance where it works. Because on the one side it often falls into "oh, we built a PDF writer, and a phone routing system, and a generalised build system from scratch, and now we have no one who knows how these work, how to upgrade them, or replace them". On the other side is "we've been running this PHP 4 project forever because the cost of upgrading every third-party library used across all the breaking changes is at least a three-year project, so we're better off not touching it" :)
