"Fake info from trusted sources" isn't a hypothetical issue. When they changed the law that required TV news to be factual we quickly headed down the path of Fox News and MSNBC. They are so effective precisely because Boomers grew up fully trusting news sources.
You can argue that it is not a problem and that people know the difference, but we have plenty of real-life proof to the contrary.
