My guess it's just the emergent behavior that results when a company doesn't provide developers time to fix bugs.
If their week is already booked full just trying to keep up with the roadmap deadlines, a bug ticket feels like being tossed a 25lb weight when you're drowning.
You could say: "but have pride in your work!"
But if your company only values shipping, not fixing, that attitude doesn't make it through the first performance review.
You’ve just described AGILE development, a way for product owners to backlog code rot while empowering developers to feel like they have a say in things.
What I've found to be most effective for program management is to set aside a maintenance team separate from the feature teams. The roadmap is then planned without counting anything for the maintenance team and they deal with bug tickets as they come in. Rotate the assignment periodically so that every developer has to occasionally spend a few months on the maintenance team.
