Well… Let me tell you some people doesn’t have that much time to game at once…specially the ones that didn’t get a gaming computer or console which this would benefit.
On the other hand I guess the free tier has queues so not sure if it would help for those.
Yeah… The only good thing of offering free tier is to fill gaps of unused machines during low usage hours, as they otherwise have the machines unused. Of course it only makes sense if that makes you money, like people testing it that eventually subscribe, having ads on it or similar.
