This is factually incorrect.
They can sell it for whatever price they want on other platforms.
What they can't do is sell the freely generated Steam keys on other stores for less than the cost of selling them on Steam.
So they cannot put a game on Steam, then generate 100 free keys and put them on Greenman Games for 30% less than Steam. They can definitely put it on Epic for 30% less and let Epic pay the hosting and distribution.

I personally set tabs to 2 spaces, but then thats the beauty of tabs over spaces. You can have two or four, or even eight if you hate yourself without impacting anyone else.
People who demand spaces are Republicans, they want to force their 2/4/8 space rule on you even if it is inconsequential.
