We already give so much money for your Switch, and $60 games as well. Many, both children and adults do NOT want to pay, just for Online play. Keep it free, people are happy with how the Switch is right now, don’t ruin it especially with Online strict games such as Splatoon 2. Majority of people bought the Switch because other consoles have a paywall locked online service, whilst you had it free, which is why many are loyal. Don’t do this.
