I don't think China has grudge against Wikimedia specifically, the official policy of theirs has always been that if you recognize Taiwan, you are no friend of them. I don't think the Chinese delegate there cares about free knowledge, further it's their job literally to say no to Taiwan recongition anywhere on earth.
So why should we be surprised that China does this when the United States federal government don't call their Taiwan ambassador ambassador, but rather director of the American Institute in Taiwan, out of respect of the same policy.
