That is pretty awesome. I didn't realize you could run battle.net on Linux. Last time I looked into this though was right before D2:R came out and was trying to get it working on Pop!_OS. Can't remember much, but I do remember not really being able to get it to work.
Glad to see that things have progressed. I don't own a steam deck, but I'm definitely filing this away as something that is possible to do. However, I'm really enjoying D4 on my xbox. :)
Looking at the data collection categories in the ios app store for Threads is terrifying. Similarly, mastodon collects nothing. General population doesn't seem to care though given the number of signups that Threads has received in the last few days. People are happy to give their information away.
