"Can" an FA "demand" the window shade be closed? The FA can "demand" that I put a bag over my head and cluck like a chicken, and as far as I know, I am required to comply with crew instructions. I can secretly think the demand is idiotic though.

As far as being considerate, I don't know why it is only people who want to watch movies who are deserving of consideration, while people who would like to see the view or to read a book are supposed to take one for the team. Support literacy, bring a book. The junky "edited for content" movies that you've already seen anyway will always be there.

Is there any business class overseas flight that would not automatically include the eyeshades?

I guess I vote, as long as there is no compelling safety reason, the sucker -- I mean, the passenger -- willing to pick the window seat should at least have control of the shade. I'm happy to give that up and to stick with the aisle, to avoid that closed-in feeling. Somebody paid a lot a money or spent a lot of loyalty points for that window seat.
