They've got bills to pay and wages to keep knocking out. You can't really blame them for converting to a more stable currency when there's no shortage of real world costs to meet.
what they should really do is using those bitcoin to pay bills directly, there must be something that let you do this, instead of dumping for fiat all the time
bitcoin should be sent from one entity to another without any conversion, it would remove the dumping altogether, it should also rise the price substantially
