It seems the general approach here is very lenient from a federation viewpoint: any representational expression, language and visual arts, are considered higher magic by this definition, and not merely what falls under the common label of "magic and occult". This means humans are actually banned from "the general use of language and figurative representations". Most modern media do not channel higher beings or are the expressions created by someone at the bodhisattva level or above (arhat for magic which controls infernal spirits). So this means it's now banned and will be stopped after repeated offenses.

This would be the reason why Gensokyo said only 3 religions are allowed: Christian Ritual, Islam and Shinto. Those all have rituals and general behavioural practices which can be performed without the use of language itself, but rather by repeating or chanting "the sounds of language" without any attached intent. By this would mean the repeating of the text of holy books with its general original meaning preserved, or the use of mantras where applicable.
Modern society would be unable to use language from now on, unless the meaning is channelled from above (in this case unless federation approved).
