Unless google owns Paypal, I don't see the logic behind your 'idiot' remark. Paypal has been around for years and years and millions of people trust their information to them. Anybody who has used eBay more than likely has a PP account. On the other side, Google is a search engine company that makes money on advertising and selling information about peoples search habits.
I can trust PP to keep my information secure and private. With google who knows what they would do with my information. Probably sell it to the highest bidder I would assume.
