I can’t imagine the PS3 will last much longer than this. Truly the end of an era. :(
Once again begs the question why Nintendo shuts their stores down far sooner and makes it so you can’t re-download your old purchases, other than greed/laziness. 
It’s not laziness. Why sell you the games when they can exclusively rent them to you instead?
You can redownload your purchases on discontinued Nintendo platforms.
Sure, but if I already got an old Super Mario game on the Wii or DS, I can’t just re-download it on my Switch. I have to pay for Nintendo Online to play the games. It would be easy for Nintendo to see if I already own a game in their library of available games and allow me to play them without paying for the subscription. They also could make more games they already released on older Eshops and make them playable. The emulator to play old Nintendo games is right there on the Switch! But yeah, why sell the stuff once if they can just rent it to us anew every couple of years.
So their stuff there’s no excuse.
Third party stuff they can’t do without contracts.
I don’t have an Xbox, so I don’t know if they only offer backwards compatibility for first party games? If no and they offer old third party games, then there is no excuse for Nintendo! If Xbox can do it, the biggest player on the console market can do it!
I don’t know if they do.
I do know that if they do, they explicitly had contracts in the past, when the games were published structured in a way that gives them permission to do so now. There is no way for Nintendo to do the same. They would have to negotiate new deals and it’s not actually possible to do so for more than a small handful of third party games at absolute best.
Also, Microsoft is a far bigger company than Nintendo.

You know, I thought you couldn’t on the Wii anymore, but apparently you can…? It’s unclear to me but seems I may have been mistaken when I said you can’t. TIL.
It’s quite a common misconception. The Wii Shop channel still works for downloading previously purchases titles for example.
Important to note, this doesn’t affect online multiplayer or availability on newer consoles, eg you’ll continue to be able to buy, download and play 360 titles on Xbox One / Xbox Series.
Not all games are BC so a lot of the library won’t be accessible, just to be clear.
Come August 2024 I will try to get my old 360 up and running and see if it has Uno.
Will this include backwards compatible titles o current systems I wonder?
BC titles remain available through the current store.
