Sure, not apps plural. They wanted a single, native cloud gaming app. If other devs chose to go through the time and expense of porting a game directly to iOS, rather than streaming a game to users from the cloud, that's on them. Has nothing to do with undercutting anyone. It's simply using a different technology to enable a consumer to play a game. Rather than having individual apps run directly on the hardware, the games are all contained within a single app and run on a server somewhere and then streamed to the user.
