In my case because I'd like my feet to fit into that area under the seat in front to marginally improve the comfort especially for short haul longer than about 90mins or any long haul. It is incredibly unfair that a person bringing one huge rollaboard into the cabin gets to utilise their legroom for their legs but someone who's checked a similarly sized bag and only hand carries a laptop style backpack on board should get secondary rights to the same overhead space. Placing your first and only hand carry item under the seat in front should be optional rather than required.

Depending on where you are on board you might be forced to have your bag under the seat while others in different areas have quietly stowed at least two bags up top.
