DMCA Takedown — who owns code written with Copilot

I'm in a difficult situation and trying to figure out my next steps.

who owns code written with Copilot. I've been dealing with this for about 14 months now and the situation isn't improving.

This involves content I created over the past 31 months. I do have documentation proving my ownership and timeline.

What's the typical outcome in situations like this?

I had a similar issue and ended up consulting with an attorney. It was worth the $200-300 for the initial consultation just to understand my rights.

Not a lawyer, but I have direct experience with this.

What worked for me was having everything documented. It took 3-6 months but was worth it.
