	Section 512 of the DMCA and section 230 of the CDA each protects ISPs and other content providers --- essentially providing them with immunity from liability. Which one of the following is NOT true related to these laws/statutes?
	Answers Percent Answered If John Smith writes original content in a Wikipedia entry that he makes up regarding the sanity of Isabel Jones, in which Mr. Smith claims Ms. Jones is insane for not going out with him, Wikipedia must remove the material at the request of Ms. Jones because of Section 512 of the DMCA, regardless of whether Ms. Jones is actually insane. 62.338% The DMCA section and laws are about copyright, whereas the CDA (Communications Decency Act) is about defamation --- so while they both provide protection and immunity, this immunity is in relation to different areas of the law. 9.74% The DMCA safe-harbor provision requires an established take-down/removal procedure to be posted and adhered to by the ISP/content-provider. The section in the CDA protects the content provider, there is no formal take-down/removal procedure. 18.831% Both sections/laws protect the ISP/content provider in the case when a third party (e.g., not the ISP) posts infringing or defamatory material -- the commonality is the third party, the material may be either infringing (e.g., the DMCA) or defamatory (e.g., the CDA). 7.143% Unanswered 1.948%

	Which of the following is NOT a quote from Richard Stallman. You can reason about this by understanding Stallman's basic philosophy with respect to free software.
	Answers Percent Answered Capitalism is this wonderful thing that motivates people, it causes wonderful inventions to be done. But in this area of diseases of the world at large, it's really let us down. 62.987% It's clear that other problems such as religious fundamentalism, overpopulation, damage to the environment, and the domination of business over government, science, thought, and society, are much bigger than non-free software. But many other people are already working on them, and I don't have any great aptitude or ideas for how to address them. So it seems best for me to keep working on the issue of free software. Besides, free software does counter one aspect of business domination of society. 5.844% For personal reasons, I do not browse the web from my computer. (I also have no net connection much of the time.) To look at page I send mail to a daemon which runs wget and mails the page back to me.

I fear that the War on Copying could go on for decades as well. To end it, we will need to rethink the copyright system, based on the Constitution's view that it is meant to benefit the public, not the copyright owners. Today, one of the benefits the public wants is the use of computers to share copies. 7.143% Unanswered 1.299%
