Asked this question before but I didn’t have the right legal words.

What law is it that allows people in the public domain to have their business publicized in contrast to regular people who are not in the public domain being legally protected from having their business publicized?

There is now law that protects private individuals from true and accurate reporting about themselves, as long as the information is legally obtained. The difference between private and public figures comes when you get into the realm of false information. Private individuals only have to show that a false statement is actually false to prevail on defamation claims. There is a general principle, established by courts, that public figures have to meet a high burden of proof in defamation cases, showing that the person reporting showed “actual malice” in reporting what they did. Because of this, supposedly private information is more freely reported about public figures.
