Victor posted the announcement as a Google docs link in the app’s discord this morning.
Basically they said that developing two apps was slowing down development.
Specifically on Linux support they said this:
We’re also exploring what Linux support might look like for Vortex in the future. While getting every game and mod working on Linux might not be possible, it’s an area we want to keep evaluating where it makes sense.
This sucks. I was waiting for the Nexus Mods to support more games. It was the one hope of having an easy tool to mod games in Linux. The new https://www.nexusmods.com/about/vortex does not support Linux and they will look how the Linux support could look like in the future… which does not sound promising.
It is possible to use vortex on Linux, I know SteamTinkerLaunch supports it for example.
But yeah not as nice as a dedicated Linux app for sure.
