Rhetorical question - yes you did. We've got logs.

Saying "I use {insert your favorite flavor of Linux here} and a piece of
closed beta software wasn't packaged for me" gets me going because it's stupid. Would you be complaining if they said "we're building Steam on Arch first, and then we'll spread out to some of the more popular distros"? Also, I suggest you check your AUR repositories because I've read that someone has already deconstructed the *.deb and repackaged it for Arch. And it works. The god damned thing works.
