What is with Square and the story of someone sacrificing themselves for the greater good, a guardian to protect them, only to probably find it a sham, lately. It seems to be a common story for them in the last 5-10 years.

I really don't like this stance of telling people to emulate if you think they shouldn't support a company. Not supporting a company really should mean not engaging with their media at all. It's such a half measure to say you're taking a stance...
If you're buying used games and systems, you're still supporting them indirectly. You're preventing someone else from getting the used device or software. They may then go buy new. If you really want this to stop, stop buying their stuff...
