What better way to gain access to users' files than through a startup's free app that demands your password?
So even outside of this surveillance stuff I don't get the point in using them.
Another significant advantage is that they support a stable command line client for Linux.
I still haven't found a solution other than (http://meocloud.pt, which was implemented by my former colleagues) that was within an order of magnitude as fast and/or as light in terms of CPU load, _and_ that supported Linux directly (let alone had halfway decent MacOS support).
After setting up monitoring around the client to keep it running we wound up switching to a different, more reliable solution.
Dropbox works ok on the server but I wouldn't rely on it as a step in any important workflows unless the client has improved significantly in the past year.
If all you need is folder/volume sharing between two machines, samba or nfs (or something similar) works great, but as I mentioned the reason for attempting to use dropbox in that fashion was to integrate with a workflow already being used by another team.
I know it's CS 101, but neither Google Drive, iCloud, or OneDrive do this.
Not to mention the other services have bizarre naming limits (e.g., dotfiles are forbidden on OneDrive).
Also, DropBox supports Linux officially.
Dropbox LAN Sync still requires the local network to have Internet access, because it can't sync anything locally without a connection to the master Dropbox server, i.e. if your office goes offline, LAN Sync will not work.
As anecdote I have zero acquaintances using any of these. Mainstream are Dropbox, Google Drive, Box.com, Microsoft OneDrive, Apple iCloud and Amazon Drive. That's already Top 6 and combined they probably cover more than 98% of marketshare.

Your experience is not the same as everyone else's. Do a Google search for "cloud storage" and you'll see all the ones I mentioned coming up in lists in the first page of results. If that's not "in the top 10", I'd love to know your definition. Oh, right, you already gave it: "Well I've never heard of it!"
Oh, and they always supported the big three OSes.
These last two features makes them stand out against the myriad of alternatives. (Especially the offerings from Apple, Google and Microsoft are laughably bad.)
Dropbox is more expensive but not that more expensive given that it just works.
That said, I switched a couple of months ago to Seafile (the German branch) and it has worked almost as good as Dropbox.
The reasons for switching were: not based in the US, supports more OSes, Rice, cheaper.
Some features like selective syncing do not work as well but others like multiple libraries are a solid addition.
I have run into a Git repo issue on Seafile that I never had on Dropbox and the client on Windows could not sync some files due to the filenames (luckily those could be renamed).
It's the only service with decent cross platform support, and by that I mean first class Linux support is a 100% requirement.
And Dropbox is among the only ones with Linux support.
I switched all my data (about 250Gb) to them from Dropbox a couple of months ago and it has worked out well enough.
Features:
- servers not based in the US
- encryption
- privacy
- open source (thanks lima)
- multiple libraries (like multiple separate Dropbox folders)
- nice file manager for unsynced (parts of) libraries
- price
- payment options (Bitcoin)
- supports more OSes
- one can run one's own server
Cons vs Dropbox:
- syncing problems not always obvious
- some UX issues
- photo support
- selective sync cumbersome (if not using libraries)
- no LAN sync
Totally distributed, works like magic. Being distributed means you do have to blindly trust a third party, but also that don't have to worry about $ per megabite. For example, one of the machines I have in my Syncthing network is a Raspberry Pi with a 3TB drive getting a backup of my laptop $HOME and important stuff from other machines all the time.
I love Syncthing, though, but I had to take the Pi out of the pool.
So I definitely wouldn't store very sensitive stuff on SpiderOak either but I guess it's slightly better than dropbox.
Feature-wise sync.com looks interesting, but there seem to be very few users out there. I would be worried that they disappear when they run out of VC money.
In my mind Dropbox became a company not worth supporting when Rice joined Dropbox's board (http://www.drop-dropbox.com/). Personally, with a board member who advocates warrentless surveillance it seems unlikely that we share similar views on the security of my data, and I wont be using their service.
