On the other hand though, that's exactly the argument being made by people who demand that the shades be closed so they can sleep "just because you need it to be perfectly dark no one in the cabin can look out the window? Perfect example of "me, me, me". If somebody wants to make sure they can sleep, they should bring an eye shade and ear plugs. Then they know they'll be able to sleep through whatever minor annoyances they encounter from other passengers. If somebody's ability to sleep is sufficiently sensitive that an eye shade an ear plugs aren't sufficient for them to sleep, then they could consider an over the counter or prescription sleeping pill. I see it as being no different than somebody who knows they are going to be cold bringing a jacket. It is simply using a little foresight and being proactive to give oneself a more comfortable travel experience. It is entirely possible for people who want the window shade open to have it open and for people who want to sleep to sleep both get their desires at the same time. I have far more sympathy for people complaining about glare on screens, but that's a much more minor issue based on the commentary in this thread.
