For me, it's quite simple. I'm not going to pretend that Valve is my buddy and are all benevolent. That being said, yes, people want to bring up HL2, DRM, and how Steam got started. Point is, they worked at keeping the PC gaming market alive, when others, such as MS, and the wonderful Epic, turned their backs on it. For Valve, this is their world. For Epic, it feels like they just want to swoop in after Valve, and have a piece of the cake after the work was already done. Who's to say what happens if/when that Fortnite money dries up, or the next great console arrives? Is Epic in it for the long haul? Will they turn their back on PC again? Of course, that future is uncertain. Given history, and what's currently on the table, I prefer to place my trust in Valve. If Epic proves they are worthy, then they'll garner the trust down the line as well.
