Wikipedia is about free content. As Richard Stallmann likes to say, free content is about freedom. And freedom is a package. There is no such thing as half freedom. People get killed in Tibet because they asked for freedom. We can't truthfully talk about freedom while ignoring them. We have to do something for them, at least saying that their struggle is right, that they have the right to stand and ask for freedom. Like everybody, Tibetan people have the right to ask for democracy, to speak their language, to practice their religion and their culture. How could we ignore them?
