I will never fly Swiss airlines again, I actually blame them for thi situation, I was on a flight 2 years ago New York to Zurich, had same issue with the person in front pushing seat back. Spoke to cabin crew who would do nothing about it. Then in opposite row same thing happened with 2 ladies, seat went back , argument , and then the lady behind poured her coffee over the one in front, then fight erupted. Swiss Airlines can pack economy like chocolates in a box, that's the issue they have extra seats in place that makes it so tight that these issues occur.
