Don't think fairness really enters into the picture. They have a business to run, it will cost XX dollars to crack the NA Focus and develop a tune for it, then they have to hope they can recoup the costs from tuners who are willing to pay for it... maybe they did the market research and decided it would be unprofitable. Who knows. I can assure you, if there was enough money to be made and a high enough demand, someone would develop a tune for the NA.
