Here’s the Twitter thread discussing this
Basically, some different apps were linked to the official steamVR app. These apps are hidden, but the data miner was able to grab some assets from them that included some custom art for Waydroid, which is a Linux program that lets you run Android apps on Linux.
Additionally, I’ve seen comments saying that some valve devs have been making pull requests for the Waydroid github, but I don’t actually have a proper source for that.
genshin already runs on linux, as the anti cheat pressure lessened in genshin in like 3.8.
also the android version of both wuthering waves and genshin do not have controller support, so they would be very bad examples to port to linux
