> Their last-minute objections claimed Wikimedia’s application was incomplete, and suggested that the Wikimedia Foundation was carrying out political activities via the volunteer-led Wikimedia Taiwan chapter
So seems China has a problem with that the Taiwan chapter is being used for political activism, rather than just serving/working on Wikipedia. Similarly if the Catalan chapter did activism in favor of independence, Spain might react to that in one way or another.
I don't know about the Catalan chapter, but the Catalan wikipedia itself leans towards Catalan nationalism.
For example, https://ca.wikipedia.org/wiki/Catalunya describes Catalonia first and foremost as a "european country", while German wikipedia and most others describe it as a region/autonomous community in Spain.
