Without strong net neutrality rules, an ISP can interfere with a user’s access to content online – that could mean, for example, blocking controversial content or discriminating against a competitor’s site. We’ve seen it happen before. In 2007, Verizon Wireless blocked text messages from the reproductive rights group NARAL. That same year, Comcast was caught discriminating against an entire class of online activities by limiting file transfers from customers using popular peer-to-peer networks such as BitTorrent, eDonkey, and Gnutella. Net neutrality has benefits beyond free speech, too: It also promotes innovation by guaranteeing small startups have the same visibility and access as established corporations, a principle that allowed companies like Google and Amazon to compete when they began.
