The vast majority of the time I agree with your posts but I don't agree with your point.
The customer doesn't have to read the CoC. Before you click on the tab to review and purchase you have an option to click on the fare rules. A pop up will give you the details. Many airlines will provide a full refund if you cancel shortly after you book. Some midnight, some 24 hours. A passenger who reviews the emailed confirmation and doesn't like the terms can probably immediately cancel.
A customer doesn't have to read a long document every time they purchase a ticket.
Change fees are a result of airlines looking for revenue sources to offset the kinds of money losing fares DIS look for. Some of the fares DIS post won't be profitable even if you add $150 to the cost of the ticket. Look at the price for a fully refundable ticket. Passengers who pay a change fee, and fare difference, are still getting a discount off the price of a full fare ticket.
Famlies should either book airlines with small or no change fees such as SW or wait to book until their plans are firm. Passengers shouldn't think they can book as soon as an airline posts money losing sale fares but expect the flexibility of a full fare ticket.
Few airlines are making a profit. Airlines aren't profiting
greatly from the misfortunes of customers
Airlines are charging high change fees for customers who want to make a change in order to allow them to charge low fares to customers that don't make changes.
is a hostile business practice
I don't agree. The airlines are using change fees from one class of customers to subsidize the fares of others. How many posters are complaining about SW fares? Numerous threads are started from DIS that aren't happy now that SW doesn't always offer rock bottom fares. SW doesn't have change fees or fees for checked luggage but you can frequently get better fares from other airlines.
AC has different fares, with different change fees.

Airlines want to use a fare sale to attract new bookings. Give some of the blame to the passengers who used the change fee "loophole" to rebook at a lower fare for the increased change fees.
A compromise might be to have a lower change fee with the customer paying any fare increase but getting no credit if the fare went down. This would make logical sense
but I doubt it could be sold to the public as being fair.
Delta's Domestic General Rules Tariff (domestic contract of carriage agreement) is a 58-page document. And it doesn't say anything about the $150 change fee, only that Delta may charge "an administrative service fee" (change fee).
The actual fee is in the fare rules, not in the Domestic General Rules Tariff.
Telling people that they need to be aware that they are bound by the contract of carriage is good advice. But that doesn't mean that every customer needs to read the document every time they buy a ticket.
The change fee has been going up over the years.
The legacy carriers are betting that most customers will not be concerned about the possibility of having to change the tickets at a later date.
The legacy carriers hope to benefit from the customers' illnesses, family emergencies, problems at their destination, employment pressures, and other unforeseeable events that will force their passengers to reschedule flights. It's now usually $150 per ticket plus and the fare difference. That's $600 down the drain for a family of four (and that's before accounting for any fare difference).
Yes. It makes sense that cheap tickets are tied to a commitment. A reasonable fee (such as the $50 that airlines used to charge), no refunds (except in the case of death), and completion of travel one year from original ticket purchase seem like a fair commitment to me.
Hoping to profit greatly from the misfortunes of customers is a hostile business practice.
