On European carriers, they seem to be more likely than other carriers to act as if the airplane seat recline should be at least somewhat under the control of the person seated behind the passenger.

On other carriers, it's more likely considered that the seat is designed to recline and the passenger seated behind the reclining passenger should just tolerate it.

If carriers don't want passengers being able to recline the seat at any point during the journey, they shouldn't buy reclining seats and see how that goes for them in getting/keeping customers and getting/keeping the regulators/legislators off their backs.
