I think also one has to distinguish junk fees (which are frequently unavoidable, but hidden after the last minute from the consumer) from things like buying food. I mean, some airlines on some flights include free food. But food has little to do with flying itself, and if you don't want to pay, you can easily get it on the ground from another place and/or wait for 2-3 hours without a meal. It's not an "extra fee", it's buying a different product - which yes, can be sold by the airline too, but I don't see anything bad in that. Conflating providing some optional services with the nefarious practice of junk fees is not helping the consumers at all.
