Hello,
Given the increasing focus and concern on data transfers and data storage locations it makes sense the Dropbox should extend the option to choose the storage location on all accounts not just the ones that are paid for. I appreciate that this feature is a way to differentiate accounts between free to paid (and a way to make money) but the rights of the data subject are still crucial. I know Dropbox have all the relevant documentation and standards however that is not the same as having your data in your own country/region.
