Agreed.
The article even states that US mobile game sales in the US were $11.8 billion. It neglects to mention that Apple takes 30% of sales their platform (which could reasonably be half). So, that number is 15% too high. Then it fails to point out that that's the entire pie in the US.
Nintendo's sales last year were more than half of that entire pie.
Admittedly, Nintendo has been taking losses, but to produce a profit under those circumstances, a huge chunk of their staff would need to be cut (hardware devs would be unnecessary anyway) and that doesn't look good to any investor.
