Critics of the legislation, which was later vetoed by California governor Gavin Newsom, argued it would hamper the development and release of open source AI models. The piece noted that “open source” had been used to describe AI models with a variety of different characteristics. The Trump administration has since removed that blog post, two sources familiar with the matter tell WIRED. The Internet Archive’s Wayback Machine shows that the July 10, 2024, FTC blog titled “On Open-Weights Foundation Models” was redirected on September 1 of this year to a landing page for the FTC’s Office of Technology. Another post from October 2023 titled “Consumers Are Voicing Concerns About AI,” authored by two FTC technologists, now similarly redirects back to the agency’s Office of Technology landing page.
