I know many people think petitions don't do any good, but it is a visible coming together of collective disdain and worry. It is, however, also by no means all we can do.

Contact and support third-party publishers. Try to get them on board.

Contact and protest Wizards and Hasbro (politely).

Make posts on social media, groups, blogs, discord chats, and wherever possible to get maximum reach.

Tell players, clubs, organisations and societies. We need to reach beyond the hobbyists and creators directly affected and let the more casual D&D people know what's going on.

As I've said before, my reach is a bit limited on social media, so much of this depends on you spreading the word and getting more people to sign.
