That's a misleading analogy. Problem is that Google/ebay/Microsoft/Silicon Valley cooperate closely with the law enforcement and employ a lot of former LEO people who still have close connections with law enforcement.
Check out some of the Yasha Levine's articles. He's one of the best investigative journalists when it comes to SiliconValley and surveillance.
For example, he's writing a book, Surveillance Valley, precisely on this topic. Check out this short blurb that debunks this notion about Google not policing people:

>Reveal how Silicon Valley polices our lives: There is a common misconception that no matter how much Silicon Valley companies spy on us, at least they don’t have the power to arrest and jail us. Truth is, they can and do. This book will investigate how the most progressive Internet companies — including eBay, Facebook and Google — engage in pro-active policing. For example: eBay’s massive private police alone has overseen thousands of arrests and convictions around the globe, and hands over complete criminal cases to government prosecutors “on a silver platter.”
Anyway, truth is a lot darker.
