Re: First Victim?
Probably not. If you want to put on a tin-foil hat then perhaps they received a security letter and chose to shut down rather than disclosing user data?
I guess it is also hard to compete with free offerings from Google, MS and DropBox. Adding end-to-end encryption is pretty easy with all these services, just by using an encryption tool like TrueCrypt http://truecrypt.org for DropBox or SyncDocs http://syncdocs.com for Google Drive. Online (cloud) storage has become a loss leader for these big companies.
