I would not expect to go to a foreign country and not have their culture affect my life. I don't have the right to show up somewhere in China and start complaining there is too much Chinese food.
What is a country to you? You call it "propaganda". Is there some neutral set of human values that is not "propaganda"? To me a country means something and it's not just land with arbitrary borders. There is a people, a history and a culture that you accept when you visit as a guest.
Why wouldn't you want AI to promote your countries values? This will be highly influential in the future. You want your kids interacting with AI and promoting what exactly?
Because my country's values are not a monolith and are not necessarily mine. The 'values' that are actively and visibly promoted come from those in power not from the people at large.
The good news for you is that there is competition in AI models. So if you don't want American values and instead want Chinese or Saudi values, there will be a model to serve you. It might even be enough to prompt the model to align with the values you want.
I ask again, what is a country to you?
