> I'm glad this is where the store's cut is going to, instead of perpetuating the Windows monopoly and lootbox gaming

Valve is practically the ones that mainstreamed lootbox gaming with Team Fortress 2, Counter-Strike, and Dota 2. When others like Rocket League have removed lootboxes from their games altogether, Valve don't bother. The lootbox "winnings" being tradable and having an item marketplace (in which they take a cut of all transactions), makes it even more egregious to me.
