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.

Emails revealed during a case
That only applies if you’re selling Steam keys in the other store. If you sell access via other means (like direct download), you can price them however you want. Hence, thousands of itch.io games that are cheaper than their Steam versions.
No, not true. They specifically mention its not just steam keys in their released emails.
If you have a link to the actual emails, rather than a YouTube video for it, I’d be very interested in that.
