Glu to blame for the end of Nintendo Wi-Fi Connection for Wii and DS?

[Tek7@Work]

Glu ceased licensing out GameSpy's networking technology at the beginning of this year. It had already drawn the ire of clients who still relied on its middleware and services by late last year.

Nintendo, which had relied on GameSpy in the prior generation -- Wii and the original DS -- had already announced that its games for those platforms would cease functioning online as of May 20.

Is Glu to blame (at least, in part) for the end of Nintendo Wi-Fi Connection for Wii and DS?

Looks like it.
