Tell that to the woman hiding from her abusive ex-husband who has already tried to kill her before. If she purchased to a gun to try and defend herself from him, now the Times has a database of exactly where she lives.
Tell that to the criminal looking to steal a gun. He now has a checklist of houses he can watch to find out who lives alone, what their schedule is, when they leave, etc.
Tell that to the undercover cop and his loving family. If someone's looking for revenge on someone against the guy that arrested him/their brother, there's a good chance that same last name is on that map somewhere.
