That kind of attitude disgusts me. Like it's someone else's job to have a sense of accountability. They would not remain employed in my company.
When I developed software I would jump right on top of any bug reports immediately, and work until they were fixed. I was grateful to my customers for bringing them to my attention.
It is different when you have a billion customers, all with different setups. At that scale, you notice real defects through product telemetry, support ticket volume, or trusted channels. You receive a high volume of bug reports that are due to user confusion, misconfiguration, or misbehavior of other software on the device - where solving an issue for one customer doesn't result in improvements for the other billion. Triage, filtering, and winnowing are necessary here.
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.
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.
Doesn’t this lead to problems like the feature team pushing buggy code and having no accountability or responsibility to deal with it?
My preference is to treat the defects like feature work, size and plan. Yes you might not get all the feature work done but the team is accountable for everything they make
