The GUI version was working a month or so ago, but a recent Tumbleweed update broke openVPN when using port forwarding via natpmpc. Bug report here https://bugzilla.opensuse.org/show_bug.cgi?id=1236718
Wireguard on the Proton GUI client on Linux is experimental, don’t use it except for testing. Use the manual setup, and make sure to test for DNS leaks.
I would be interested to know why you are pushing this product across multiple places on Lemmy. Your post, despite disparaging “viral marketers”, has a viral marketing tone with statements such as “I feel like I’ve been wasting money on my VPN ever since I found Riseup”.
Additionally, while I do believe a free VPN using an autonomous collective, resource pooling approach is a great idea, in practice this VPN has had… not a great history from my point of view. A quick search shows that in 2017 they were forced to comply with US Law Enforcement https://en.m.wikipedia.org/wiki/Riseup, see the Warrant Canary section. VPNs based in the US are known to be at risk, and this is another good example.
When choosing a VPN provider, server location is important, as well as company location. You are repeatedly encouraging people to Torrent from a VPN based in one of the most zealous countries opposing file sharing worldwide, and one that has already worked with Law Enforcement.
