For a half-second I thought this might have been a pro-anonymity law.

Illinois' law was motivated by a doxxing attack on a business that subsequently shut down. The UpRising Bakery and Café was doxxed last year after it planned an all-ages drag brunch, which triggered threats of violence against the bakery's owner, Corrina Sac, and vandalism of the establishment. Goldenberg told Ars that the doxxing "tore apart [Sac's] business" and, after the bakery closed, ADL raised nearly $50,000 through a GoFundMe campaign to help her recover.

This is confusing though. How do you doxx a business and public records? Article doesn't really go into the technical definitions of the law.
