Dropbox is stuck syncing after an update, what can I do?

From what I've read in this thread, it seems the Dropbox update has caused widespread syncing problems.

My guess is that Dropbox does not have adequate server capacity to handle all of the re-syncing that is being requested, and that explains the low download rates users are experiencing.

Unfortunately, it's unlikely Dropbox will acknowledge this, because it would imply they need to offer some form of compensation to users for not providing the service level paid for.

So instead, Dropbox appears to be running a disinformation campaign portraying the issue as caused by users, such as the symlink problem that keeps coming up in support messages.

Ironically, Dropbox's advice that users keep trying to re-sync simply maintains the overload of server requests, perpetuating the problem.

But Dropbox makes millions from many users, so the delay is not much to them. However, individual users who cannot access files are losing productivity and reputation in their own work, which matters a lot. Dropbox needs to understand that.
