So a guy, who has a Bachelor in Biology from 1970, that has worked since then as an Artist (Painter) put together a little pdf with some info he got from wikipedia and that's what you call a "published study"?
I call this utter bullshit.
Btw, how does he explain Brazil having so high numbers without a G5 net?
Obviously, not explaining it at all.
Edit: This is not how science works.
