This. Firaxis is a western game devoloper who created a western game series about "doing an imperialism" which is meant to provide a very loose abstraction of all of human history and which has always operated from a very western centric view of World History. That is the Civilization series..
Though more recent titles have tried to be more inclusive, the realities of modern history are inescapable. Our "modern age" is defined by Western imperialism, colonialism, and technological advances/maritime expansion. You're not going to escape that reality in the Civilization series either, whether it's smacking you in the face in the form of Moteczuma donning a suit and tie in an western themed industrial age ala Civ 3, Colonization/revolution mechanics modelled on the Americas ala Civ IV, or the game ending in cataclysmic clash of European born ideologies ala V. This is a western series attempting to abstract all of human history into a game about imperialism at its core.
Asking Firaxis to make victory paths feel "less western" is like asking Jane Austen to make her novels "more black" or asking James Baldwin "hey where are all the straight, white male character?" It's just fruitless. Instead of arguing about the victory paths being "too western" it's probably makes more sense to argue about how the restrictive design of eras and their accompanying victory conditions will force the players into the same exact historical narrative every single game and turn what used to effectively be a very customizable long form sandbox 4x campaign experience into a glorified terra map script with short themed scenario packs for rounds.
