Totally true. Change fee elimination is not the same as change for free, fare changes apply and most of the tie the airline is better off but just looks better. Change fees are a relic from the 70s when there was an actual administrative workload involved with changing dates and fares were ... fares, i.e., not dynamic but fixed and published based on a route. With the advent of technology and dynamic pricing the cost of a change is just baked in and letting your customers rebalance based on price sensitivity (e.g., let someone give up a cheaper seat so that someone else can buy that same seat at a higher price) again helps them out
