Me either, although a few years ago I sold some weapon skins and loot boxes that I received from playing CS Go when it first came out for enough Valve bucks or whatever to buy a couple of new games!
As much as I like Valve, Valve is one of the major player bringing and normalizing Lootboxes into games. Even before the Lootboxes was a thing on smartphones, let alone before they arrived on other AAA games as well. I think this is the worst contribution of Valve to videogames. And this statement comes from someone who usually defends this company.
