"Public domain" refers to old works whose copyright has expired (in the U.S. that's 100 years since author death). That's not applicable here.
Edit: parent comment prior to deletion had said that websites should be public domain.

If parent wanted to say that all publicly-accessible web pages should be considered legally scrapeable without triggering federal cybercrime legislation ... sure, I think that's a reasonable point of view, and roughly the EFF's point of view in this case. If, in the process of scraping and reusing data, you are infringing copyright (or breaking a civil contract, or whatever), that can be dealt with on its own, not by criminalizing the scraping.
