The fact that this hasn't happened before should tell everyone that this is not business as usual. No other government in the world has caused WMF to respond in such a way, which leads me to believe that this case is not as obvious as you say.
Also, due to license terms of Wikipedia, by deleting the page, individually and collectively, Wikipedia editors are being denied their rights as authors. This may be a copyright violation in India, in the jurisdiction of the editors, in the legal jurisdiction in which WMF/Wikipedia are incorporated in, and/or all of the above, that is to say, worldwide.
