I speak as someone who is also 2m tall but who never puts his knees up against the seat in front of him (and views that as a little childish). My perspective is that the airline has made the seat-space smaller in order to make the flight cheaper, and has gifted everyone with a button which allows their seat-back to not be vertical, for the convenience of those who wish to sleep on a plane, at the expense of the convenience of those who wish that seatback to be up for whatever reason (honestly it's more an issue for me with using a laptop than it is for my legs, which can fold or tuck longways underneath the seat in front of me or stretch into an aisle or many other things). I don't think there is either a "right" to recline nor a "right" to not be reclined on; rights are not the correct word at all. Blame is not productive here; it's a matter of perspective who is infringing on whose rights, and the truth is that we live in a negotiated world, and this is just one of the negotiations that needs be made. I do like the idea that us can't-sleep-with-that-engine-drone-anyway folks have a laptop-column in the plane which doesn't recline, for our mutual convenience. Until that's the case I'll ask the person ahead of me politely and/or request to be reseated into an exit row.
