In the US a lot of questionable filtering is done because of religious or common concepts that are not very sensible but do influence the amount of money a company can make. For example, a christian religious group might take offence to software containing other religions, and if that group is big enough, they might consider not buying anything from a company until a change is made. This basically goes for any subject and any group, but in the case of the USA, a lot of normal things are considered taboo by many groups of people (i.e. sex ed / sex health / pictures of bodies / alcohol / everything that is not american). Because some of those groups can be very large and very influential, 'normal' things get banned or ignored by those groups and as a result less money is to be made.
