"but why would you trust a VPN provider more than an ISP?"
You probably shouldn't. There are most likely laws against your ISP from listening in on your traffic, not for your VPN. If the government wants to listen in it doesn't matter, your VPN service is forced to cooperate anyway so you haven't gained anything.
If I'd use a VPN I'd make sure to use one that is in another country, probably making it a bit harder to connect the VPN and ISP to you that way - but hardly bulletproof.
