"Comcast's conduct also threatens innovation by undermining the end-to-end principle. The Internet has enabled a cascade of innovations precisely because any programmer -- whether employed by a huge corporation, a startup, or tinkering at home for fun -- has been able to create new protocols and applications that operate over TCP/IP, without having to obtain permission from anyone. Comcast's recent moves threaten to create a situation in which innovators may need to obtain permission and assistance from an ISP in order to guarantee that their protocols will operate correctly. By arbitrarily using RST packets in a manner at odds with TCP/IP standards, Comcast threatens to Balkanize the open standards that are the foundation of the Internet."
