The next step they should do is make TMR hall effect sticks mandatory in all controllers.
The amount of e-waste these console makers are producing because of sticks going bad is disgusting. Then people having to buy new overpriced controllers because old ones losing accuracy.
This problem was largely solved decades ago. Dreamcast was doing hall effect in 1999.
This only reason it's not being done today is largely corporate greed of continuing the perpetual cycle of planned obsolescence for the sake of further profits.
€35 million is probably nothing to Nintendo, they likely pay their entire legal department more but at least it's a start.
