Nowhere in the airline's advertising blurp do I see "when travelling in economy you may be subjected to hours of agonising discomfort should the passenger in front of you wish to recline their seat. This is what you paid for".
Give me a break
Give who a break?? "Agonising discomfort", aside from being somewhat self-contradictory, is a ridiculous overstatement.
How about this?
"We offer reclining seats to all our passengers as part of our customer service package. When travelling in economy class some of our taller and/or larger passengers may experience discomfort should the passenger in front of them wish to recline their seat. We remind our customers that all passengers have equal rights to comfort and service they paid for, no matter what side of a reclining seat they may be on."
