No, the thing they're doing is still awful.

The basic problem is that they do actually have competitors and are offering a product which is basically fungible, so their margins are inherently going to suck, even if they do every slimy thing, because then their competitors will just do the same thing and they're back to having thin margins only now they've made everything more deceptive/inconvenient/confusing.

The ideal thing in a market like that is to have an efficient way for customers to cut through the BS and find the best price for a ticket that isn't screwing them in covert ways, because then the deceptive tactics don't work, which takes away the incentive to do them. They'll still have thin margins, only with less deception.

But an individual airline can't unilaterally allow that if their competitors have a way to block it or they'd be at a competitive disadvantage, so they're going to try to stop that from happening. It's in no one's interest -- not even theirs -- to let them. They just need you to not let their competitors get away with it either.
