“So what was my concern and what about Google for that matter?
I became an entrepreneur during the 90’s, the boom time of what you might now call Web 1.0. Yahoo created a directory of all the sites they could find without asking anyone for permission. Ebay quickly became the largest auction company in the world without having to pay a portion of revenue to any ISP. Paypal became the most successful payment company and Amazon soared in e-commerce also without such tolls or any particular company’s permission.
Today, starting such a service would entail navigating a number of new tollbooths and gatekeepers. If you are interested in this issue I recommend you read http://futureoftheinternet.org/ by +Jonathan Zittrain. While openness is a core value at Google, there are a number of areas where we can improve too (as the book outlines).
But regardless of how you feel about digital ecosystems or about Google, please do not take the free and open internet for granted from government intervention. To the extent that free flow of information threatens the powerful, those in power will seek to suppress it.”
