Any ideas to prevent the fatal update from taking effect? eg. Run Steam in Offline mode and block IP's? Could someone sue Valve for pushing this out and breaking their PC? The damages being the total purchase price of all the games to which access is lost? (Didn't someone win a lawsuit a while back against Microsoft after they auto-uograded her PC to Windows 11 without her consent?)
