Netflix can safely remove any film without damaging the costumers; films are tipically just 1h to 3h long, experienced in a single shot.
A videogame is a different experience, it may last for hundered of hours... what if a game you are playing is removed from the Gamepass without any notice?
Games leaving Gamepass don't also leave the Xbox Marketplace, they are still available to buy digital (and in many cases physical). Savegames are also compatible between physical, digital and subscription versions... since they are all the same for the system.
So where is the damage for the customer who played the game on GamePass from day one and buys it after the GamePass removal for $10 - $30 compared to the customer who bought it day one for $50 - $70?
