I daresay that after ten years of discussion NANOG has reached 
consensus that implementing BCP38 is a good thing and that all 
networks should be encouraged to do so.

Net neutrality has not been discussed completely to death yet but I'm 
pretty confident in stating that squeezing consumer connections 
further down each time some blog hypes up yet another "The Internet is 
melting!" threat won't scale.

I don't think anybody would disagree with this statement.  Netgear did 
get into action when they DDoS'ed a university's NTP servers; perhaps 
similar sticks can be shaken in this case.

(Is Netgear one of the brands involved?  Usually they're better.
  Pardon me for not reading the whole thread and the other five)

Two posts up in this thread we were talking about net-wide blocks 
without individual proof of open relay or equivalent status.
