Right.

Classical Newtonian mechanics predicts that light will bend with
twice the angle observed.

Relativistic Newtonian mechanics however predicts the correct
angle since it is now understood that only half a photon's energy
is sensitive to transverse interaction.

Agreed. Outright falsehood. Probably plain ignorance on the part
of this author.
