Thanks, I see another poster found a link to a statement they have on their site about it now it seems.

There is a particular leaks site that also called out Proton for routing their connection thru a similar shady service in the past.

The other service was Radware. The problem some people had was not the tech (it uses GRE tunnels that doesn't compromise our TLS), but that Israelis are allegedly shady. We don't think that's a fair characterization. We have switched from Radware for other reasons in 2018.
