Is this a feeble attempt at fighting the UK antitrust case?
about a decade ago, when Blizzard was in court with Valve over the latter taking the reigns of "DotA", this would've been unthinkable.
Funnily enough there have been a few times that Wine specific problems have been addressed by the BNet team (pre steamdeck) and when Linux players were accidentally banned they have unbanned them iirc in some scenarios.
