When McDonald’s started asking “would you like fries with that?” their sales and profits exploded. That really happened.
Now let’s get theoretical. Imagine you were a potato farmer, and your friend was a cattle farmer. You both have an interest in selling as much of your product for the highest price possible.
You might try to promote potatoes, because that’s good for you. “French fries are going to become the main course, and burgers are going to become obsolete.” Well, no, that’s not supported by the data. That doesn’t mean that fries aren’t good for McDonald’s. Sales for both went up. People buying french fries didn’t buy fewer burgers. The effect was additive, not canibalistic.
Of course, does that mean that either is “good” for the industry? Does that mean it’s “good” for consumers? Is it fearmongering to point out the health risks of eating fried potatoes and ground beef every day, or how bad factory feeding people is for the economy?
Subscription gaming isn’t going to replace traditional games. But it has become a significant part of the industry. If that’s good or bad depends on your perspective.
