Why is the same thing called Sundae at KFC and Sunland at McDonald's?

The reason why KFC calls the same thing Sundae and McDonald’s calls it Sundae:

As early as 1897, Americans were eating "Sundae" ice cream. It is said that "Sundae" ice cream was invented by a Wisconsin ice cream shop owner named George. George was unconventional and poured cherry syrup on the ice cream and put a candied cherry on it and sold it to customers. At first, this mixed ice cream was only sold on Sundays. Later, people found this ice cream very delicious and the demand grew, so George supplied this ice cream to people every day. Since this ice cream was originally sold on Sunday, the shop owner named it Sunday. ?

But Sunday is Jesus’ Sabbath (Sabbath), and the church believes that using this day as a product name is blasphemous to the gods. Therefore, Sunday had to be renamed Sundae, which is still used today. In order to avoid taboos, Sunday ice cream has also used some other names, such as sundi and sondhi. ?

The reason why KFC calls the same thing Sundae and McDonald’s calls it Sunland is first of all because of different transliterations and because the two companies want to differentiate between each other’s products.
