I think this is an out-of-sight, out-of-mind kind of issue. They simply don't understand how their noise, which they do not perceive, can be so detrimental to others. Moreover, a lot of people simply can't grasp the difference good hardware or even just a different setup (moving away from noise sources like fans, open windows, appliances running, etc.) can impact the quality of their sound. Lastly, a lot of people either cannot or think they cannot do anything about it, so they dismiss others' concerns because "everyone else has problems too", equating their noise to be the same as others'.
