Agree. But changing criteria so also means, VPNs will go from “hide your traffic from ISPs” to “hide certain traffic from ISPs, some of the times”.
Is “killswitch” necessary to the model that goes “hide your traffic from ISP”?
To me, it does seem like on OSes that provide a “killswitch”, the end-user must be (as a minimum criteria) given an option to enable it by VPN clients, regardless of whether the OS implementation is up to the mark or not.
PG doesn’t have to write about VPNs as something they are not then:
Should I use a VPN? Yes, almost certainly. A VPN has many advantages, including: Hiding your traffic from only your Internet Service Provider.
Without a “killswitch”, I don’t think a VPN can lay any claim to accomplish that (a client-side guarantee is hard to provide without a client-side implementation to match). In fact, 2 of the 4 points PG makes for why one must “almost certainly” use VPNs are not sound, I don’t think: Mention kill switch leaks caused by OS limitations - #4 by ignoramous
