I fimd the range of the pivot is limited, and if the person in front reclines I have no option but to do otherwise, and thus the domino effect starts. Long-haul post meal service on an overnight flight ... this is to be expected. Short-haul on day flights ... it is a little bit selfish unless the pax is trying for a power-nap.
I flew trans-Tasman last week in row 4 and both times the busness pax in row 3 reclined as soon as the seat belt sign went off and stayed that way until landing. Whilst this didn't have the same impact as it would for other economy rows, it was annoying to have the curtain pushed back over my legs and the pax in 4A could no longer slide past me so I had to leave my seat everytime they wanted to get in/out. The J pax wasn't sleeping - just throwing their seat around because they could.
