I'm not part of the "SAO hate train" that spawned years and years ago but i'd rather rewatch/recommend the GGO alternative series instead of SAO proper
if i had a business that made a steady income, even if it wasnt huge, i would never make the decision to give up any amount of that control to outside parties who dont care about the product
the only thing you really get out of going public is an injection of cash, but if you are able to make a steady profit, the "advantages" of going public just seem pointless to me
