Mainly because of the issues of data access, site removal and the emphasis on "foreign" sites. It boils down to accessing and disseminating proprietary data, which includes that under commercial copyright, but also a host of other proprietary data that is or can be accessed and distributed by the same people using the same illegal means, from bank PINs to weapons schematics. The main difference is how much criminal prosecution to which people in those two examples are already subject.

In terms of the means and intermediary sites involved, however, many of the same principles apply. I am not sure what, if any, legal repercussions there would be a to a site or its operators if it "facilitated" people obtaining or distributing the blueprints for an MX missile, but under the proposed legislation would impose significant criminal penalties for that as surely as for facilitating mpeg downloads.

As far as the necessity, the ease with which I CAN (NOT have) already obtain copyrighted material online at no cost establishes that.

As far as inevitability, establishing that is more a matter of researching public knowledge than these specific bills.

Again, I did NOT say these specific bills are inevitable; I said A new law is inevitable, which it is, for all the above reasons.
