I’ve found little difference in long-term maintenance time between rolling my own and using third-party services/libraries in practice.

Services change and go away.

Libraries change and add complexity to the build and project.

One of the greatest fallacies in modern software development is how much everyone seems to completely ignore the time, complexity, risks, and long-term maintenance costs of adding so much third-party code and infrastructure to everything.
