Ok I will jut bite and ask: what does this mean? A vpn running

It allows you to use a public hotspot without having to worry about people there snooping or sniffing or trying to mitm you.

The price you pay is that your traffic goes through Google VPN servers, yes. However, seeing how you probably use Chrome or something already, and a bunch of other Google services that do data mining and telemetry, it's not that big of a deal.

tl;dr Google provides you with a VPN so you can use public unencrypted wifi in hotels and coffee shops and public parks or wherever
