Pai said he was "pleased" to see the federal government's lawsuit, and that "The Internet is free and open today, and it will continue to be under the light-touch protections of the FCC's Restoring Internet Freedom Order." US Attorney General Jeff Sessions asserted his belief in the power of the federal government, saying "Once again the California legislature has enacted an extreme and illegal state law attempting to frustrate federal policy. The Justice Department should not have to spend valuable time and resources to file this suit today, but we have a duty to defend the prerogatives of the federal government and protect our Constitutional order."

According to the LA Times, California state AG Xavier Bacerra said the state is prepared to defend its new law, and that it would need additional funding and staff to implement the regulations.

Weiner said in a statement that "Today marks a true win for the internet and for an open society." Stanford professor Barbara van Schewick said "Like the 2015 Order, SB 822 ensures that Californians, not the companies they pay to get online, get to be in control of what sites, apps and services they use. SB 822 bans ISPs from blocking, throttling, and charging websites fees for access to the ISP's subscribers or for fast lanes, which will protect California's economic growth, innovation economy and democratic engagement."

The move has also been opposed by ISPs like Comcast and Verizon (the owner of Engadget's parent company). Industry group US Telecom, which counts AT&T and Verizon among its members, issued a statement from president & CEO Jonathan Spalter, who said: "We all support strong and enforceable net neutrality protections for every American – regardless of where they may live. But this bill is neither the way to get there, nor will it help advance the promise and potential of California's innovation DNA. Rather than 50 states stepping in with their own conflicting open internet solutions, we need Congress to step up with a national framework for the whole internet ecosystem and resolve this issue once and for all."
