What better reason to hide something than because you think people will exploit that knowledge to harm you? You don't even need to think the party you're giving the information to will abuse it. Can you trust them to not pass it on or have it stolen from them? We have many many examples of why you should not.

I've shared this (or similar info) with landlords and realtors and platforms that I don't trust. That's life.
The point is that just because you have something to hide doesn't mean you've done anything wrong. You might end up sharing that information in certain situations, but carefully. The framing those who promulgate that phrasing want to push is that not wanting to share information with the government makes you suspicious, because your only possible reason could be wrongdoing. This notion is hostile to liberty and security.
