the attack requires someone to plant a DHCP server into your local network... i guess if you are using wifi out and about that can be done anywhere... and i guess that's gonna have to be fixed for other devices as well

it's not relevant to your home network or one competently run, but there's plenty of dodgy stuff out there

i don't see any specifics about VPN apps though... is this all, like openvpn, pptp... wireguard throws up a higher priority network device and establishes the connection outbound so i can't see how this would work on wireguard
