People are afraid to share anything that talks bad about Samsung, because they believe it will affect them negatively in the future when searching for jobs or such.
It sort of does, but of course it's all politics. If the Secretary of Health and Human Services (HHS) (under whom the FDA operates) or an interested outside party petitions the Attorney General (AG) for a review, HHS (through FDA) studies the issue and reports back. If HHS recommends against controlled the substance, then the AG shall not control it, i.e. it's "de-scheduled". Otherwise, it's pretty much up to the AG and DEA to decide how to act on the recommendations.
