What did you expect? The DS and Wii have been out for 10 and 8 years respectively.
Whenever a new system, support for the old system is dropped. It's not like Nintendo is the only one that does this either.
When EA brings out a new Madden game, the Madden game from just the YEAR PRIOR TO IT has its online support cut off almost immediately.
Playstation recently cut off all online servers for the game MAG (which was an online game only, so the game is completely worthless now), and that game came out in 2010.
The point is, online servers cost money, and when you have new systems that are getting all the games (they don't make DS/Wii games anymore), you can't afford to keep running old servers.
Also this is a tech support forum, not a place to rant. If you want to rant, rant elsewhere
