I'm seeing a lot of posts about losing bitcoin on blockchain.info.  It seems that everyone is ready to blame themselves, but is the company really running some kind of scam?

If they are, does anyone have an INFORMED opinion as to why customers would not be able to successfully take them to court or arbitration to recover their assets?  FYI, "Blah blah blah, I bet they have T&Cs" is not an INFORMED opinion; a company can't use T&Cs to magically change theft into legal behavior.
