iot-ftps-client is not a FTPS client without ssl_implicit=True. Correct?

Looking at [source](https://github.com/dgonzo27/py-iot-utils/blob/master/iot-ftps-client/iot/ftps/client/_client.py#L82). Isn't calling iot-ftps-client a FTPS client highly incorrect or even fraud, if it uses insecure plain FTP when instantiated without `ssl_implicit=True`? Sorry if I am wrong.
