This just shows that it's important to buy systems that don't come with a proprietary operating system pre-installed. It's bad for your freedom. Instead, buy systems with a free GNU/Linux distribution like the FSF-endorsed Trisquel distro pre-installed. Try to support companies that at least try to do the right thing. If you can't help support freedom, then at least buy a computer with no operating system, that's at least neutral. If you can't do that or at least remove the drive and erase it beforehand so that nothing is found to boot from and thereby short circuiting the whole "I must click agree" deal.
