I’m not backing off my argument; I’m arguing from a stance of reasonableness rather than perfection. And while we can argue on exactly what defines “reasonableness”, I think it’s unambiguously clear that a large number of people do in fact need 50% of their traffic to come from a single peer and I think it shouldn’t be unreasonable to expect an ISPs to address that rather than throttling customers. I know plenty of people whose internet usage consists of email, Facebook and hours upon hours of streaming Netflix.
