Information hygiene is like spacecraft sanitization
Space agencies thoroughly disinfect the spacecraft in fear of not brining microbes over to extraterrestrial biomes with devastating consequences. This is likely do in response to the ignorant behavior of European explorers on American land who brought harmful microbes and disease, having devastating effect on the indigeneous population. However, the same is happening unwillingly with memes, as global communication platforms enable the selection of memes unbound by geographies. This diffusion of spatial bounds is made extremely vivid in one of Greg Egan’s short stories.
