Just make the Ad blocking extension retrieve an extra file outside of github automatically(default on, but leave it configurable like the other filter lists in options) or I am sure there are custom lists based on easylist or other lists available already on the net that include/can include
But props to the creator of this, great ingenuity.

Latest easylist:
https://www.eternum.io/ipfs/QmdDtvs1QaQQG6NMpc2cpncA4zVZqgUK...
If you decide to use IPFS for distribution of your list, I'd be happy to donate some Eternum credits so you can pin it.
He's blazing a trail that others who may be more risk averse or have more to lose can then follow. Actually blocking these domains is kind of a side benefit, especially since the most likely people to download the extension are those who could just as easily achieve the end result themselves in other ways.
Unfortunately there is no legal concept of waiver in this situation: the other side can pick and choose weak targets at will and avoid someone who will fight back. Just one more critical flaw in the DMCA system. Contrast this with trademark law where one must universally enforce the mark or risk losing it entirely.
Edit: replaced https with h||ps to prevent it from showing up as a link (which are apparently cut off if they're too long).
