That's a very niche use case compared to the majority. Also, opposition research has got nothing to do with "I asked about [political event] and it refused to answer" kind of complaint. Opposition researchers don't ask LLMs about Tiananmen or whatever. The latter kind of queries are still just testing censorship boundaries as a form of virtue signaling or ideological theater, to make some rhetorical point that's completely decoupled from the vast majority of practical use cases.
