Raymond @ 2015-10-08 14:41 UTC (permalink / raw) To: bloat I meant everything I said in that comment - I don't think dtaht's worthy effort rang the "national security" bell anywhere near hard enough, either as a matter of substance or as a rhetorical move. But I was also thinking tactically about how my comment would implicitly reposition the others. What I think I've done here is change the debate's Overton window - extend the range of thinkable proposals - and thus made the Taht/Cerf and Perens proposals look conservative and moderate. dtaht, sorry about not being involved in the last day's editing but I got to a point where I thought writing my own broadside would actually help yours more than a bunch of minor revisions. -- <a href="http://www.catb.org/~esr/">Eric S.
