> It's not clear to me why the VPN people are more trustworthy than ISPs.

In my country, the UK, ISPs are legally required to retain logs of customer activity for 12 months. A VPN has no such legal requirement.

So while I can't be 100% sure that my VPN is monitoring me, I can be 100% sure my ISP is. Additionally, my VPN has a financial incentive not to log customer data, or at the very least, not to be caught doing it.

(I'm currently using IVPN (https://www.ivpn.net/). It's on the more expensive side, though that isn't necessarily a bad thing, and it supports multihop over OpenVPN, and the experimental Wireguard protocol.)
