It is rather that many software developers see how bad the code is, and thus attempt to reduce the code debt if possible. I have rarely seen software developers fixing things that aren't broken (though it is often not easy for managers and people who are not deeply knowledgeable about the project to see why what is there is broken).

On the other hand, I have seen politically very adapt software developers who actually rather want to managers to advertise some technology that they would love to introduce in the projects.
