Yes, that's much more credible - thank you for sharing that. This part in particular is concerning:

The ruling makes particular note of "a Steam account manager [who] informed Plaintiff Wolfire that 'it would delist any games available for sale at a lower price elsewhere, whether or not using Steam keys [emphasis in original complaint].'" The amended suit also alleges that "this experience is not unique to Wolfire," which could factor into the developer's proposed class-action complaint.

I wasn't able to find any instances of Steam actually de-listing a game because it was listed cheaper elsewhere, but a credible threat to do so is almost as bad (possibly worse, really, since such a threat hints that Steam might have used other underhanded tactics when dealing with game devs). I wasn't able to find any more recent news on the case, but hopefully we'll learn if the issue was that particular Account Manager + lack of oversight or something more.
