I attended a small demonstration shortly after noon today for the Internet-Wide Day of Action to Save Network Neutrality.
The main argument offered was that if big telecom companies are allowed to set up fast lanes for other big businesses that they own or that pay them off, ordinary consumers will not find their competitors. So it sounds like an anti-trust argument, and similar arguments have been made against Google and search engine results. Speakers also noted that major Silicon Valley companies support neutrality and that major startups have developed during this period. Senator Ed Markey (D-MA) led the event. But then look at Timothy B. Lee’s recent Vox piece, “The End of the Internet Startup”.
Another major argument was that network neutrality helps minority voices (people of color, LGBT, and immigrant) voices be heard.
