SAN JOSE—A California state court judge is poised to reject a conservative content creator’s claims that YouTube functions as a public forum, and therefore, must protect free speech rights. 

Prager University, a nonprofit founded by conservative media personality Dennis Prager, claimed YouTube’s censorship policies violate California’s Unruh Act, the Lanham Act, and the state constitution’s speech and association statutes, according to the first amended complaint filed in May.
