First off, it is very easy to get cryptography wrong. I wouldn't trust most people with being able to implement cryptography software correctly.
Buzzwords like AES and SSL are used to convey a sense of security. Their 256-bit SSL uses AES-256 to encrypt data in transit. While using AES-256 to encrypt a file doesn't mean it is secure. The mode of operation is very important. The following wikipedia page has a picture that was probably encrypted with something like AES-256. I will let you guess what the original picture was.

Another issue not discussed is key management. To encrypt the files with AES-256 they need to have the key. If someone breaks into their server, the server will have the key and the files. It becomes easy to break the security.
