I recently tried my hand in commercializing my open source project, gitleaks (http://gitleaks.io). I'm keeping the core gitleaks project MIT but changed the gitleaks-action on GitHub to a commercial license. Revenue from the commercial license and maintenance agreements has netted me much more than donations I've received over the past couple years. I encourage any open source maintainer to try and find a business model (plugin, dual license, enterprise support, etc) for their project.

FWIW, here is a blog post explaining the rationale behind starting an LLC https://blog.gitleaks.io/gitleaks-llc-announcement-d7d06a52e...
