There were rumors they were going to launch an email service, then a basecamp competitor, then it was a race against iCloud and Google drive...
Honestly after cancelling my account I've never looked back. I get more storage per dollar with google and iCloud and the Dropbox macOS integration is a joke.
With all the acquisitions Dropbox has made in the past decade, they couldn't have created a more useful macOS app? Read a blog post by any former dropbox employee and you'll hear the same thing over and over:
Dropbox is littered with management problems and their leadership has no idea what the future of the company and will look like because cloud storage is a race to zero.
