Recording DNS queries is a long standing method of spying on end users that ISPs and governments have at their disposal. In the US we have a constitutional amendment about how it's supposed to be illegal for law enforcement to mess with people not suspected of a crime - the fourth amendment. They don't really respect that rule at all, so it's in everyone's best interest not to give them metadata when it's avoidable.
