Do you understand the "why" of stand your ground and castle? It is an extension of self defense justifications. Self defense justifications are for protection against crimes that result in intentional, direct, grievous harm to a specific person; things like rape and murder. Online interactions just don't bear those consequences in any normal case (maybe at some point for connected medical implants); certainly not in the case of Sony protecting itself from monetary loss. Anyone trying to extend SYG or castle that direction is undermining the entire justice system. SYG, castle, and self defense exist because the justice system is not fast enough to protect victims from irreversible damage from the most heinous of crimes. Property loss can wait on investigation, prosecution, and judgement.
