In a recent interview with Edge Magazine (reproduced via (Awful version of ERA)), Sweeney doubled down on the argument that UWP is part of a long-term plan to lock gamers into Microsoft's distribution net.
Tim Sweeney: The risk here is that, if Microsoft convinces everyone to use UWP, then they phase out Win32 apps. If they can succeed in doing that then it's a small leap to forcing all apps and games to be distributed through the Windows store. Once we reach that point, the PC has become a closed platform. It won't be that one day they flip a switch that will break your Steam library – what they're trying to do is a series of sneaky maneuvers. They make it more and more inconvenient to use the old apps, and, simultaneously, they try to become the only source for the new ones.
