Hi, Hack Club member + previous summer intern here. Hack Club is incorporated in California and headquartered in Vermont. I am very much not a lawyer and am not speaking for Hack Club in any official capacity, but since California has some ironclad consumer protection laws, I wouldn't be surprised if your idea holds merit. In the meantime, a self-hosted fork of Mattermost is our only realistic option for maintaining comms after Monday that suits all our needs.
