Why? Just store your files locally in the encrypted vault, which will be synced with Dropbox. And you could even use MountainDuck for the communication between Dropbox and your computer, so you don’t need the Dropbox software (and all the tracking/analytics) at all.
(I use onedrive but same principle applies)
Mainly just that, there’s no way to access files except thought the vault software. Other apps, third or first party, can’t use them. I can’t see them online or use any web documents/shared documents. It basically turns cloud storage into a syncing app, but I can just use syncthing for that.
