I'll play devil's advocate and argue that this could just be the code equivalent of privatizing the benefits while socializing the costs. You mention that your team writes code without explicit discussion of its quality. The benefits of that choice are front-loaded, while the costs of that choice won't be apparent until later. Furthermore, the team members who have to pay those costs may not even be the current team members - it may actually be those on the team months or years from now, after the original code authors have left for greener pastures.

So it may be too early to declare that your choice was a successful one. As the article mentions, code is read much more often than it's written.
