Hate to rain on the Linux parade here, but didn't the article say: "There are no ways to prevent such attacks except when the user's VPN runs on Android." and that Linux was just as vulnerable as Windows?

It's not as vulnerable but it still is.

Interestingly, Android is the only operating system that fully immunizes VPN apps from the attack because it doesn't implement option 121. For all other OSes, there are no complete fixes. When apps run on Linux there’s a setting that minimizes the effects, but even then TunnelVision can be used to exploit a side channel that can be used to de-anonymize destination traffic and perform targeted denial-of-service attacks.

You can also use network namespaces on Linux which Wireguard has a nice explanation and walkthrough on, recommending this as part of setting up wg connections. https://www.wireguard.com/netns/

I saw that but unfortunately it doesn't detail how to set it up persistently on every boot. And I also haven't seen anybody using this method, probably because of the lack of tooling around it. For example afaik the official Mullvad client on linux just uses a firewall.
