They could, but there is very little evidence to show that a dislike for subscription models outweighs people's desire to consume quality content.
Evidence is strong that people follow the content they want, and then secondarily choose the least friction delivery model.
I still support this law. If they move to subscriptions to “dodge” this law, that’s fine in a way. At least consumers won’t be under the false impression they own something in the rare case they’re paying a subscription to play a game.
