I think they’re trustworthy, but not the best in all those categories - I think tuta is better for mail (no dependence on google services), mullvad is better for vpn (linux app actually works with wireguard, and doesn’t have a hard dependence on networkmanager), and keepassxc + syncthing is better for passwords, although to be fair I haven’t tried proton pass
The epistemic status of that person saying it vs me is not all that different, neither of us have evidence to present
