19 days agoThe purpose of this add-on is solely to circumvent access restrictions to copyrighted works. It is clearly a circumvention tool under the DMCA and therefore illegal to distribute in the USA.
The policy violation is that it breaks US law.
Guessing here, but Mozilla likely blacklisted it to disable it for all those who had it installed and cover their ass legally. Nobody can accuse them of aiding in the distribution of this illegal tool anymore.
While uBlock could be used for the same thing, it has a different primary use (blocking ads, which is still legal), so a similar charge against it might be successfully fought.
The DMCA is a fuck.
My guess: The blocklist is the only way they have of removing it for all those who download it from them when they previously distributed it. And they do that so they can not be held liable for those copies.
A company like News Corp might go “This was downloaded 50 000 times from you and can be used to bypass access control on 10 000 000 of our articles which would otherwise cost $20 each. So we are suing you for 10 trillion dollars in losses. See you in court.”
