That is absolutely not fair. BER-TLV is really nice protocol. I have worked with it for couple of years when I worked on an EMV application. It uses BER-TLV to communicate with the credit card but it is also very convenient format for all sorts of other uses and I would use it wherever I could. Think of it as Json but in binary form. It is not complicated and I would not even bother parsing the messages -- I could interpret hex dumps of them by sight very easily.
