I think in this thread you're conflating taking credit with mentioning, which are two very, very different concepts. I would not expect you to give credit, but I would expect you to mention relevant competing technologies for a compare and contrast. :)
If you look above in this subthread you'll see the following comment:

I don't think I was conflating. Or at least, if I misinterpreted, then so did at least one other person. Which suggests that the original comments were very open to such an interpretation.
