I went as far as emailing the TypeKit team about it a while back, and was fobbed off with a meaningless reply.
Getting back to your question, Photoshop used to have a range of Swiss type faces that could have been used for the sort of banner headline applications Helvetica is associated with, but that has also gone. Bickham Script Pro, for instance, is a font used by one of my wine producing clients, so I was not impressed when that disappeared after CS6. I was excited when TypeKit was introduced, but later became disillusioned when I realised how many useful fonts were no longer available with CC.
It has pretty much become a font class nowadays, but there are sans serif fonts in Photoshop that will do the trick. Further to what you have already been told, you might like to check the Wikipedia entry for Helvetica
