Not an option for me, I'm mostly using Mullvad inside Tailscale.

I use Tailscale to connect my various sites together as a single LAN and Mullvad sits inside Tailscale and is the only VPN that doesn't break my virtual LAN.

I use Mysterium on a separate desktop fedora Linux box as it isn't included in my VLAN and so I get a chance to test it as a user. Something that interests me as I've been providing Mysterium exit nodes for several years now and earning enough money to fund my broadband and VPNs 😂
