1 - Xbox has had backwards compatibility for a while. So it has lessen the blow of their pushback to people.
And if I'm not mistaken, a lot of Xbox and 360 games will still be available.
I believe every game deserves being preserved, but I'm seperating my opinion here, because I'm talking about the public in general, not me.
2 - Pushing back against Nintendo for doing it, is like pushing back against a serial killer for killing another 20 people.
If they are free, the serial killer will do serial killer things.
Point is, that disgusting disregard towards gaming preservation, is what they have been doing for a LONG time. Nintendo will do Nintendo. They will pet you on the head from time to time, and give you the obvious and super popular older games of theirs on Switch, but beyond that, they don't care.
People feel sad (I literally cried when the 3DS store closed), people feel angry, but at the end of the day, it's Nintendo. They are as anti-art as a gaming company gets (Being against art, WHICH IS WHAT VIDEO GAMES ARE, being preserved, is anti-art). And people know that.
Sony, on the other hand, has nothing.
They don't have backwards compatibility.
And they seem pretty neutral towards gaming preservation.
Which is why people tend to push back audibly to them.
And the fact that they care enough to delay the closure of these stores, shows that your voice matters at least a little bit to them.
You scream to people that listen to you. You talk to people that listen to you.
The ones that don't, some will try, but most will just feel the way they feel, and that's it.
