So only one of 6 have been overturned. And the others have existed longer. 
In fairness there was no confrontation in those states. Texas likely got the bonk because of requiring the disclaimer being a bridge too far, but the ruling explicitly blocks the age verification portion as well so it could be used as precedent against the other states now.
Virginia came later, for what it’s worth.
