Hypothetical question

Quick background on my situation — any input appreciated.

open source code in commercial product. I've been dealing with this for about 3 months now and the situation isn't improving.

This involves software/code I developed over the past 31 months. I do not have documentation proving my ownership and timeline.

What's the typical outcome in situations like this?

Have you tried reaching out to your state's labor board? They sometimes have free resources or mediation services.
