I have had quite a bit of experience in trying to communicate with Chinese native speakers, including some from the mainland, who are trying to use English. I have always valued that communication regardless of the various difficulties that we have encountered with syntax and grammar. On the whole regardless of whatever difficulties this communication is especially valuable to everyone concerned.
To crab up and fall into a negative posture is simply rude beyond words. In the case of Wikipedia articles I can't imagine a more productive situation than a free-flowing and respectful relationship with the fluent English speaker sometimes editing a bit for syntax and the native Chinese speaker grounding material in Chinese reality. It's always worth the trouble.
