Needless to say this is incredibly disheartening that there is no recourse for players affected by the recent changes to the login procedures made on August 29, 2019.

There are many posts on several different internet platforms that have echoed my predicament. If the number of affected legitimate users is small, that's even more of a reason to be able to either offer specialized support or monetary compensation. If the number of effected legitimate users is high, I would behoove SE to implement the proposed change in policy so that both consumer and producer are fairly compensated.

As is referenced in the OP, the change for Windows registered users who had also purchased the Steam client in order to launch the game was not outlined or mentioned at all. The implementation of the patch is currently leading to downtime from accessing the game through the Steam platform in it's intended manner for the affected users.
