Why do people from Spain speak with a list? Well, it's not a list, but it can sound like one to other speakers. What happens is, speakers from Spain make a distinction between the letter set and C-E-C-I and the letter S. So for example, a word like beer is pronounced Therbetha. But why do we do that? Do we just want to be different? Obviously not. The third pronunciation is the original pronunciation of these letters and it goes back centuries. But why is it different in other Spanish-speaking countries? The reason has nothing to do with some king who had a list and then everybody has started speaking like him. That theory has been debunked. The reason goes back to the time of the Spanish conquest of the Americas. So at that time, the third pronunciation was spread all over Spain except for a region in southern Spain and in the Canary Islands. And this is important because these regions have big ports and this is where the fleet that went to the Americas departed from which meant that the Spanish-speaking world is that kind of pronunciation. So in other words, this first sound never really traveled there.
