>No, the purpose of this is to protect users from malicious add-ons. We have clear guidelines for when it is appropriate to blocklist an add-on and have refused multiple times to block for other reasons.
Copyright, DMCA, and legal concerns are not listed. So I take that to mean nothing will be rejected from signing for those reasons. Hosting on AMO has stricter rules, so they could sign the extension for you to host, but refuse to host it themselves.
If tomorrow Mozilla can shut down any extension, the calculus changes. Forcing Mozilla to kill ad blockers still makes EvilCorp look like assholes, but it might be successful. There's a big upside now, so much more reason to try and force Mozilla's hand.
