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.
But you can do the same with a normal desktop Firefox, none of those things prevent you from switching windows to check things. There must be some other reason why it’s run as an Android app.
The android app has native touch support
Probably because it’s got a better touch interface than desktop
note: I’ve never tried desktop Firefox in a touchscreen device
