The principle that protects free speech and innovation online is irrelevant, they claim, as blocking has never, ever happened. And if it did, they add, market forces would compel Internet service providers to correct course and re-open their networks.
In reality, many providers both in the U.S. and abroad have violated the principles of Net Neutrality -- and they plan to continue doing so in the future.
This history of abuse reveals a problem that only real Net Neutrality protections could solve:
MADISON RIVER: In 2005, North Carolina ISP Madison River Communications blocked the voice-over-Internet protocol (VOIP) service Vonage. Vonage filed a complaint with the FCC after receiving a slew of customer complaints. The FCC stepped in to sanction Madison River and prevent further blocking, but it lacks the authority to stop this kind of abuse today.
COMCAST: In 2005, the nation's largest Internet provider, Comcast, began secretly blocking peer-to-peer technologies that its customers were using over its network. Users of services like BitTorrent and Gnutella were unable to connect to these services. 2007 investigations from the Associated Press, the Electronic Frontier Foundation and others confirmed that Comcast was indeed blocking or slowing file-sharing applications without disclosing this fact to its customers.
TELUS: In 2005, Canada's second largest telecommunications company, Telus, began blocking access to a server that hosted a website supporting a labor strike against the company. Researchers at Harvard and the University of Toronto found that this action resulted in Telus blocking an additional 766 unrelated sites.
AT&T: From 2007-2009, AT&T forced Apple to block Skype and other competing VOIP phone services on the iPhone. The wireless provider wanted to prevent iPhone users from using any application that would allow them to make calls on such "over-the-top" voice services. The Google Voice app received similar treatment from carriers like AT&T when it came on the scene in 2009.
WINDSTREAM: In 2010, Windstream Communications, a DSL provider with more than 1 million customers, copped to hijacking user-search queries made using the Google toolbar within Firefox. Users who believed they had set the browser to the search engine of their choice were redirected to Windstream's own search portal and results.
MetroPCS: In 2011, MetroPCS, at the time one of the top five U.S. wireless carriers, announced plans to block streaming video over its 4G network from all sources except YouTube. MetroPCS then threw its weight behind Verizon's court challenge against the FCC's Open Internet Order, hoping that rejection of the agency's authority would allow it to continue its anti-consumer practices.
PAXFIRE: In 2011, the Electronic Frontier Foundation found several small ISPs were redirecting search queries via the vendor Paxfire. The ISPs identified in the initial Electronic Frontier Foundation report included Cavalier, Cogent, Frontier, Fuse, DirecPC, RCN and Wide Open West. Paxfire would intercept an Internet user's search request at Bing and Yahoo and redirect it to another page. By skipping over the search service's results, the participating ISPs would collect referral fees for delivering users to select websites.
AT&T, SPRINT & VERIZON: From 2011-2013, AT&T, Sprint and Verizon blocked Google Wallet, a mobile payment system that competed with a similar service called Isis, which all three companies had a stake in developing.
EUROPE: A 2012 report from the Body of European Regulators for Electronic Communications found that violations of Net Neutrality affect at least one in five users in Europe. The report found that blocked or slowed connections to services like VOIP, peer-to-peer technologies, gaming applications and email were commonplace.
VERIZON: In 2012, the FCC caught Verizon Wireless blocking people from using tethering applications on their phones. Verizon had asked Google to remove 11 free tethering applications from the Android marketplace. These applications allowed users to circumvent Verizon's $20 tethering fee and turn their smartphones into Wi-Fi hotspots. By blocking those applications, Verizon violated a Net Neutrality pledge it made to the FCC as a condition of the 2008 airwaves auction.
AT&T: In 2012, AT&T announced that it would disable the FaceTime video-calling app on its customers' iPhones unless they subscribed to a more expensive text-and-voice plan. AT&T had one goal in mind: separating customers from more of their money by blocking alternatives to AT&T's own products.
VERIZON: During oral arguments in Verizon v. FCC, judges asked whether the phone giant would favor some preferred services, content or sites over others if the court overruled the agency's Open Internet Order. Verizon counsel Helgi Walker had this to say: "I'm authorized to state from my client today that but for these rules we would be exploring those types of arrangements." Walker's admission might have gone unnoticed had she not repeated it on at least five separate occasions during arguments.
The court struck down the FCC's rules in January 2014 -- and in May FCC Chairman Tom Wheeler released a proposal that would allow discrimination online.
Since then millions have urged the FCC to reclassify broadband providers as common carriers. This is the only approach that would enable the agency to create and enforce strong Net Neutrality protections.
In the absence of any rules, violations of the open Internet will become more and more common. Don't believe me? Let history be the guide.
