All of this is right.  The idea is that the photon would gain a mass,
thereby obeying Proca's equation rather than Maxwell's.  Radiation
would gain a dispersion relation in free space; light would travel at
a speed less than c and dependent upon frequency, but it could carry
arbitrarily far.  Static electric and magnetic forces, on the other
hand, would be exponentially damped with distance.

The dispersion relation could scramble radio signals by delaying
different-frequency components by varying amounts.  Sunshine would
survive intact if it managed to get produced in the first place.
