Major actors of the Internet have become real giants: Facebook has acquired WhatsApp and Instagram, Google owns Youtube and Waze, Microsoft distributes Skype, etc.<br /> This concentration of actors creates multiple issues: what if Facebook were suddenly shut down? And how could we browse the Web if Google went down? <strong>We rely more and more on services provided by a small group of suppliers.</strong> For example, Apple (iPhone), Google (Android) and Microsoft (Windows Phone) dominate almost the entire mobile OS industry.<br /> Furthermore, the size of these actors impedes innovation: it’s hard to launch a startup that can match up to Apple or Google (the first and second worldwide market capitalisations, respectively).<br /> Finally, The lack of diversity of the giants means they can track many people who are unaware that there may be alternatives, and it can influence the kind of data you receive (a Google search will produce different results for the term “nuclear power” depending on whether Google considers you to be an environmentalist or pro-nuclear power).
