In one sense, your point and mine can be true at the same time: that radical proposals are what's going to be required to reform copyright, and that the RSC is not only a wildly inappropriate venue for those proposals but also that a single "rogue" RSC staffer had no business putting the RSC behind a policy initiative that virtually nobody in the house on either side supported. Again, you'd be right here and I would at the same time.
But in another sense, I'm saying something more about the memo; not only that it was inappropriate for its venue, but that its policy goals were dumb. The Khanna memo would not have made it any less fraught to run a consumer Internet company. It would not have prevented the content industry from leveraging potential bankruptcy against infringers. Apart from reducing copyright terms, it seemed to consist mostly of extravagantly costly political expenditures in the service of cosmetic goals.
