Rogers has no way to distinguish between Proton’s “secure core” VPN and a simpler, more local Proton VPN endpoint. In both cases they see you sending encrypted VPN traffic to Proton - they can’t see where Proton then sends that traffic next (naturally, because it’s a VPN). If Proton’s “secure core” VPN is slow but Proton’s other options are fast then that’s on Proton.
