What, do I need to start a big argument to get people posting? If it goes silent here, you'll force me to endure Facebook. GAH.
Okay... uh... how about this old gem: If you want to see who was truly influential in regard to synth use in the 70s, look at the charts. There was no internet. There was no Spotify. There was nothing. What you heard was on the radio. As such, Paul McCartney had more to do with synthesizer awareness that Kraftwerk ever did.
