The first response to my comment (by lvass) insists, with apparent seriousness, that it is literally true. I think it is not superfluous to mention it isn't. Also, how does it work as a metaphor? What are the metaphorical "infections" that "sunlight" defeats? Conspiracies? Fake news? There has never been more information available, and there also has never been more conspiracies and stupid theories about everything. So, also as a metaphor, sunlight is not a disinfectant.
