While I don't disagree with your sentiment, it seems like this list is just "self hosted open source alternatives". Even if there are better options, Gitea still falls under that definition, no?
Also curious. I left Mullvad because they stopped supporting port forwarding. Proton seemed like the best second option privacy/feature/price wise at the time. IVPN was touted highly around that time, but it appears they have also phased out port forwarding
Manjaro might be good, but you'll have to adjust the vacuum's clock every time you want to clean
