I made the claim and provided evidence. You have yet to refute it in any meaningful way and have only provided conjecture. If you have proof the email isn’t real feel free to share it. You’re also free to look up the emails yourself if you feel they would prove me wrong.

Without evidence “your knowledge” means nothing.

If you have anything but conjecture I’d be interested in that as well.

No, not true. They specifically mention its not just steam keys in their released emails.

Emails revealed during a case

Learning that steam may delist a game if its offered by another store for cheaper has definitely soured my opinion of them. GOG should make a native installer though.
