Eto electrical stores in Russia had a television advertisement where they stated that Father Frost (a.k.a. Santa Claus) did not exist.
But saying that he doesn’t exist is tantamount to telling children that their parents are liars.
So the ad has been banned.
The Federal anti-Monopoly Service said the ad had broken rules for advertisers not to discredit parents and teachers.
The ad “induces negative relations between children and parents”, Andrei Kashevarov, the service’s deputy director, told Rossiiskaya Gazeta.
I’m not sure what the context of the Santa ad was… I would think that’s relevant.
