So, Admiral—an anti-adblocker company—contacted EasyList and told them to remove a domain from their list. This domain was a server they needed for their anti-adblocker platform to work.
EasyList told Admiral that they would only do it if GitHub agreed, so Admiral contacted GitHub and the domain was removed from the EasyList list after GitHub told EasyList they should comply.
The "attack" is that any company can tell lists to remove their website via using a DMCA violation, so lists become useless.
I have two questions:
1. how would a domain name on a list violate copyright
2. why aren't lists hosted anywhere else but the US so that they can't be controlled by DMCA requests.
