Are you trying to give away previous employers customer data?
Sounds like you’re angry and looking to pick a fight. As someone who’s worked with and for multiple manufacturers and even helped create one with a partner.
I don’t recommend you do anything that would tarnish what value you have left.
As someone with a large amount of data and NDAs I recommend you take the beaten path of just adding license holders to the database I’ve shared publicly.
Do yourself a favor and don’t push the previous employers to the edge.
One similar man to another.
