They're running the servers though. They see the IP address you come in on and which hops you're going through.
All multi-hop does is increase the crowd that you're hiding in. not help you if the provider itself is compromised.

The only way to get around it is to use two VPN providers. I use mullvad on the router level, so all my traffic goes straight to them, and then to an IVPN multihop on top of that.
So they would both have to be working together in order to de-anomise my traffic. 

 Yes, this is what I was talking about.
