Free open wifi is not risky if you make sure that the URLs start with https (not with http) when you browse. Then all data sent and received will be securely encrypted. The only problem is when you want to access servers that do not support SSL.

Not true, if wifi router is cracked attacker install ssl-proxy (also known as man in the middle) to get all stuff in clear text format.
