This is actually good advice… in isolation. Encouraging people to spend their money more wisely can bring awareness to an issue but it ultimately does little to implement change. Sure, you and I (and the Fediverse as a whole) might be hyper-vigilant about these kind of things but the average consumer isn’t. Continuing with your Nintendo example, Nintendo has decades of brand recognition and a zealous fanbase to satisfy the demand. An eager gaming press will gladly take free hardware from Nintendo for positive coverage.

Real change won’t happen until the tap is turned off, so to speak. These companies are taking advantages of gaps in the law that permit them to get away with this. Antitrust law in the US dates back to a time when steam-powered trains were still common and the last breakup involved a telephone company. When AT&T was broken up, the home computer (desktop in modern parlance) was just starting to take off.

So, yes, we should spend our money elsewhere when we see this kinds of corporate abuses but until you starve the beast, keep expecting these kinds of behaviors.
