While I’m very sorry that your condition impacts your ability to perform this mechanic, you cannot say that the developers are discriminating against anyone by implementing this mechanic. I can 100% guarantee you that the developers were not sitting there at their computers thinking, “I’m going to make this mechanic specifically to screw over people with finger mobility issues BWAHAHAHA.” 100%. So, you can’t prosecute them for anything because you cannot prove that they were discriminating against anyone.
