Maybe it influenced it, do you remember 'low self steem' by offspring? that song was basically a rip off of teen spirit which was a rip off of the Pixies song dynamics (Loud, quiet, loud)
More than crediting a single artist i think this influence comes from the decade and the music movement in that decade in this case the 90's
like, music from the 70's all sound alike, same as music from other decades and they all kinda reflect the mental state we had at that time.
'creep' by STP or even the radiohead one are a reflection on the 90's and Pearl jam was just another band in that 90's movement which honestly i never liked much except from this song.

I think maybe you're giving Pearl jam too much credit cause i don't think STP sounds like them at all.
