“AT&T’s claims were and continue to be false,” Stanford Law School professor Barbara van Schewick, a prominent net neutrality supporter, told Ars. Van Schewick is also director of Stanford’s Center for Internet and Society.

The California net neutrality law is the only state-level law that matches all of the protections in the FCC rules that are no longer enforced, van Schewick said. But contrary to AT&T’s claims, she says it’s possible for ISPs to comply in California and implement other policies in different states.
