Yes. If somebody reclines in front of me, my knees have to go to the side of my seat. It's not my fault, so why should I put up with it just so somebody in front can lie at a 3-5 degree flatter angle?
Why should someone be denied the chance of some sleep on long haul simply because you refuse to shell out the relative pittance for extra legroom seating? It works both ways surely? If you have an issue that you feel you need to restrict another person using the product they've paid for, then that's not fair on them either. I can deal with the product I am buying, for those who aren't comfortable with the product they have paid for, i.e. those who feel too cramped, then surely it's reasonable to pay more rather than restrict the fairly small comfort option of the person in front, i.e. the by now minor recline.
