1) Do you have an official (or unofficial) dataset the corroborate your statement that people affected are a minority? It's an easy assumption to make sure, but you're coming off as stating it as fact. By doing so you're heavily marginalizing those of us who are suffering.
2) NTT is SE's chosen ISP. It is 100% their responsibility to lean on them to ensure customers aren't having issues. As we are not NTT customers (and neither are our ISPs) we cannot do anything. I'm not sure if you're familiar with how other game companies have handled this issues in the past (in fact Riot was very open about how they did), it is something that is commonly done. SE has just chosen to either not do it, or not pay for it.
3) It's true that SE felt a move was needed (and it was), but that doesn't mean they made the best decision for the playerbase, or even for themselves. I mean hell, they made 1.0 too, Diadem Eureka, etc. They're not above making bad, or incorrect decisions.
