I also have Linux running, Eddie alone doesn't work nicely with SELinux on my Fedora because it accesses some devices directly that userspace tools usually are not supposed to touch. Again, on my TODO is to check if it works better with Bluetit that works as a helper daemon for theses kinds of system access requirements. Fortunately there is also the option to use OpenVPN configs directly. However I found the info at ipleak.net was different when using either Eddie or OpenVPN via NetworkManager and I wasn't sure what to expect (right behavior) or what role my browser plays in it (Chrome-based vs. other).
So since Sunday I reported 6 issues, 3 of which are already confirmed and partially fixed. (This really was triggered by our conversation!) Force-killing Eddie for MacOS shutdown is now also officially reported
What I value most in AirVPN is that I feel the people know exactly what they are doing and trustworthy, software is open and using standards that allow me to even use other tools (no vendor lock-in) and there is responsive non-bullshit support, which is not a given. As it is often with using e.g. Linux or Open Source, there is some extra price to pay in time and effort but you get something in return you don't get otherwise.
