Wildtangent for Winamp - what happened?

a very long time ago i had a couple of cool-looking visualisations (i'm thinking ChristmasDancer) for Winamp by Wildtangent. i don't recall exactly what happened; i think winamp upgraded and then they wouldn't work, and then wildtangent became synonymous with malware and now you'd be hard-pressed to find an english language site that even mentions them.

what the hell happened? these visualisations were very slick, and the dancing females looked better than a lot of Poser images. and they moved in realtime and did so on my cheap-ass system. was it another case of corporate greed and stupidity?
