We (me with a friend) created this page https://openwebdefenders.org and planning to create banners for websites that may want to inform their users on what’s going on.
If anyone wants to contribute somehow or have other ideas I would be happy to discuss on https://github.com/openwebdefenders/web/issues
But isn’t it quite the jump from mozilla accepting drm from a service in an indistry that has invented drm to them accepting a blanket drm for the web? I think it’s kind of not guilty until proven for mozilla. They have so far (to my knowledge) not done anything very anti consumer.
