To security experts: Do you use #VPN for services that are already end-to-end encrypted? Or, you add their apps in split-tunnelling mode?
Or, to rephrase it: is there any use in keeping end-to-end encrypted apps behind a VPN?
This is under the assumption that all things are equal (no ISP issues; no need to bypass any network set up; end-to-end encryption is enabled by default).
