I maintain an npm module that enables react applications to authenticate against generic IDPs using pkce. I wrote this to auth against Cognito back when the Amplify packages were adding 1.7MB to the bundle size.I just noticed that somebody copied the files from my repo into a new repo, destroying all the git history. This person then added a LICENSE file claiming copyright over all the files.My repo lacks a LICENSE file but it is marked as MIT on the GitHub project page. I would assume the person can't claim license over all of my work like that. For jurisdictions: the person appears to live in Norway while I live in New Zealand.I sent them an email and haven't heard back yet. What should I do?
