Are you sure? I thought that what you describe is what packages suck as NikGapps did, while MicroG is a reimplementation of the code. It does call Google webservers, but it doesn’t run Google’s blobs (which is also why it’s severely limited/fragile compared to packages that run them)
I mean, the post is about using a Steam Deck. It doesn’t get much more effortless than that.
You don’t have to go out of your way to install a bleeding-edge distro that needs janitoring.
