In the case you shared, the name/address of the terrorism suspect was actually given to police by Apple, not Proton. The terror suspect added their real-life Apple email as an optional recovery address in Proton Mail. Proton can't decrypt data, but in terror cases Swiss courts can obtain recovery email.
Moreover, the case concerns Proton Mail not Proton VPN, and Proton VPN's no-logs policy has been proven in both independent audits (https://protonvpn.com/blog/no-logs-audit) and in court (https://protonvpn.com/blog/transparency-report).

And Proton does not inspire confidence.
