At least in the customer space, I think Dropbox's main problem is that they have refused to offer lower space / lower cost packages. I can get 100 GB on Google Drive for $2 / month. The lowest package on Dropbox is $10 / month for 2 TB. I barely even fill half of the 100GB that I'm using on Google Drive. Why would I pay 6x as much for storage that I'm never going to use?
