Using public Wi-Fi networks makes users vulnerable to data theft.

Is it true that using public Wi-Fi networks makes users vulnerable to data theft?

Partly. Several peer-reviewed and reference sources indicate public Wi-Fi networks are vulnerable to attacks and that unencrypted sensitive data has been observed in transit, while an FTC consumer article says widespread encryption now makes public Wi-Fi usually safe, though scammers and fake sites remain a risk. The evidence covers parts of the claim rather than settling it fully.
