DMCA 1201 isn't just a crap law. It's completely unworkable, as has been known since before it was passed.
Suppose Bob is in the business of duplicating public domain US government works. He downloads videos from the NASA website, presses them onto DVDs and sells them on eBay. He can do this without anybody's permission because DVDs are from the mid-90s and the patents are expired. He uses the same DVD format as Hollywood so people can watch them on their existing DVD players, but he also makes a free DVD player app for Linux so people can watch his DVDs or rip them or do whatever they want because they're in the public domain. It can also do the same with any other DVDs, because it's the exact same format. Is Bob breaking the law?
Now suppose Bob is a jerk who is doing this with public domain works without providing anyone a way to exercise their right to copy them, or doing it to enforce contractually unlawful license terms or something like that. Is someone who makes a tool to thwart Bob breaking the law? If so the law could have (more) First Amendment problems, to say nothing of the obvious unreasonableness. But if not then it's a worthless law because anyone could use that as a justification to break anything. Which it is regardless because it has never been effective at suppressing the availability circumvention tools, only at should-be-impermissible abuses like prohibiting interoperability to prop up existing monopolies.
It's also notable that NASA publishes many videos on YouTube. As in, only on YouTube.
