Sad, but true. I will not patronize an ISP that decides for me which =
packets I want
and do not want, but, apparently there are people who will.
Not sure how I feel about a more adaptive version. Sounds like it would =
be better
than the current state, but, I vastly prefer "I pay, you route. If I =
want filtration, I'll
tell you."
