Look, the lack of communication from Square is annoying. But to say this all comes down to them when the two ISPs involved are WAY bigger GIANT corporations that much on customer corporations for lunch is giving Square a lot more control than I think they may have. They may be hitting the same "muh NDA" roadblock we are. They may be trapped in a contract with NTT. Or NTT may be the only ISP that can do what Square needs them to do to run FFXIV and peer with ATT.
I'm not saying take the pressure off of them, but I am saying I blame the bigger, nastier, greedier Giant corporations more.
