All physical receptacles break and increase failures by measurable amounts at mass-production scale.

You take care of your hardware, even during "heavy use," many people absolutely do not - and are downright abusive.

Many of these parts exhibit partial or intermittent failure modes where it's more expensive and difficult to determine warranty eligibility than to just fix the problem. Peanut butter in the jack, loose solder joints, whatever.
