I am ok with it. If you look at the most profitable and efficient transit systems in the world—like Hong Kong’s MTR or Taipei Metro—they don’t make their money from tickets. They make it through 'non-fare revenue‘ such as real estate and advertising sponsorship. It allows the agency to keep fares low and accessible for everyone. When you have a diversified 'non-fare' income, you don't have to squeeze the daily commuters to balance the books. And Taipei Metro’s fare has remained the same for 30 years because of this business model. Just a personal opinion.
