Is AirVPN vulnerable to a MiTM attack by sysadmins looking to throttle their clients? According to http://security.stackexchange.com/questions/53444/vpns-vulnerable-to-mitm-because-any-certificate-goes OpenVPN does not validate that the cert is correct, thus making it possible for ISPs, sysadmins etc, to trick the client to use a fake cert so they may monitor the connections contents. Is AirVPN safe from this?
