That’s a possibility. You could also make a point that it’s cultural at this point to use steam if you PC game. The exact reason steam is used is split across many different points. However, I stand by my statement. If games like league, valorant, osrs, or anything from blizzard can exist strongly in the pc scene, I think it heavily refutes your points. For those people at least. These are all games that don’t use (or for some are mainly used by) the steam client.
