In 1928 Mustafa Kemal Atatürk started a plan[1] to ditch the old form of written Turkish (Ottoman Turkish which was RTL[2]) and implement one based on the latin alphabet in order to fight a huge illiteracy problem at the time.
Let me assure you, they know that 1 star is bad, 5 star is good. Even courses are rated between 1(bad)-5(good) in school reports. They also say that "I just rated 1 star to be seen, BUT it is a wonderful app", etc. I saw some comments like this : "I say hi to my cousin, this game is so fun. But I am giving 1 star to be on top." They are trolling and do not care or do not know about total rating system.
