This is more like the Netflix model than the traditional timed exclusives model. E.g. the platform owner also owns all content production to stuff its channel with content. In the short term this can be good for gamers (as long as the platform owner throws absurd amounts of money around for content production in order to grow the subscription base), but I can't see this being good for the long run, especially when there are only two or three big players on the market, and no more independent game developers and publishers are left (Activision/Blizzard isn't exactly a fountain of creativity of course, so that's a bad example).
