Same reason as why Google offers anti-semitic messages. Ultimately those voice assistants just act as a search engine for most queries, so they are going to respond in a similar way to a search engine. As long as they properly attribute the source of the response (I know Google Home does this, not sure about Alexa), I don't see a big issue.<p>It would be nice if for major topics (ex. COVID) there was some authoritative source that the voice assistants used, but that wouldn't solve the entire problem since there are pretty much infinite search queries that will return some kind of conspiracy as the top result.
