Does Trent not like "Capital G"?

Is anyone aware of Trent talking about not liking the NIN song Capital G? Its puzzling me because it's a great song (IMO) and was released as a single. Yet it is one of the most rare songs they have ever played live.

Song is on the album Year Zero and single came out in June 2007.

According to Setlist it has only been played live 10 times (between May-Aug 2007). Only twice after the single was released. Only once in the US at a private show.

So we have a song released as a single that has never been played live once at a public show in the US. It just seems so strange. I've looked but haven't found a reason why.

I think part of the reason is that it had disappointing radio play & sales. But the first single on Year Zero was Survivalism and I don't think that did much better. Yet that song has been played live 321 times (again per setlist).

Curious to hear what the community here thinks. Thanks!
