I wouldn't make a blanket statement like that. Depends what VPN and how you're using it and what you're doing on the internet and (in particular) what threat you're trying to protect yourself against. PIA will do a good job of protecting the contents of your messages from someone sniffing your wifi hotspot, but is useless against someone with the ability to monitor all internet traffic. The data leaving the PIA proxy is just as unencrypted as it would be if you weren't using a VPN, except your attempt to secure it will likely draw extra attention. There's strong evidence [1] that the NSA has special rules that allow enhanced collection and analysis of encrypted traffic.
