I like to try to think through each parties side. Ideally, a compromise could be made that would allow the passengers to move to a different row (bulkhead) so that everyone could be accommodated, but in cases where a compromise can't be made, I believe safety is always more important than comfort.
If I were her I could contact the FAA, DOT, the airline, and the news, because she obviously brought a compliant seat, installed it correctly, and was made to move it.
