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 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.
