I read it more as "you buy an airline because you want to run an airline, but what you actually end up running is primarily a credit card company." That doesn't mean you stop doing flights, it just means that the part you want to do is the part that loses your company money.

This sort of thing all the time when (for example) a movie lover opens a movie theater. Running a profitable movie theater is a lot less about movies and a lot more about maximizing concession revenue.
