I think it's worth mentioning that even if an easylist filter entry counts as "circumventing a technological measure that effectively controls access" -- which I think is debatable for multiple reasons -- the DMCA takedown procedure only covers copyright infringement. It does not apply to anti-circumvention measures.

As Admiral's blog post points out, Github recommends using the same contact procedure for anti-circumvention takedown requests as for normal DMCA takedowns. But as far as I can tell, they're doing so purely on their own initiative; such a takedown request doesn't have the force of law in the same sense that a claim of copyright infringement does.
