Unfortunately, it's inevitable, since presenting a regular file explorer looks like they're competing in the commodity file syncing / backup space, not the higher-value enterprise collaboration space. They're trying not to be a "feature" as Steve Jobs called them.
Enterprise collaboration is going to use what integrates with their email - that's going to be OneDrive or Google Drive. The commodity syncing space was where DropBox shined, and it feels weird taking a step back from that.
I'm a paying customer and I just realised that I'd not been using my Dropbox on my rebuilt laptop for >6months. I gave up with the crappy view. That's pretty bad if I only just noticed!
I'm glad I'm not the only one. And once I close that window with Cmd+Q, I have a mild panic attack that I closed the actual service that was in the middle of a sync and may have lost some data.
[I'm being polite :)] I've been unable to find anything to make an informed opinion on what they mean by end-to-end encryption, which is prominently mentioned on the home page etc.
[I'm not being polite. #BeingThatGuy :)] My best guess is that they're using their own definition of end-to-end encryption. i.e., SSL for transit + encryption at rest = "end-to-end encryption". Whatever.
Every time I encounter this I reconsider my Dropbox subscription.
