Why we should include this into the repository, i.e. what does it do that the alternatives do not? - GUI option for ProtonVPN services to act as an addition to protonvpn-cli or an alternative to the aging Qomui package.
Is it open source? - Yes
If it is open source, please provide a link to the most up to date, versioned source tarball/zipfile - https://github.com/ProtonVPN/linux-app/releases/tag/0.7.3
Not even necessarily expecting that this will be approved for inclusion, but just wanted someone to reach out to the devs to see about get eopkg support going along with the likes of .deb and .rpm support.
