I think we have an ideological disagreement here. I'm not part of the "open source" movement, I believe in free software. Although I'm not prolific, I have authored some free software and shared it widely. I want people to have it, use it, and share it, so long as they extend the same rights to their users.
Now my software has been assimilated into a proprietary blob. Had that blob been free, like my software within it, I would have accepted it, but it's not. It's controlled exclusively by Microsoft and OpenAI, two entities which I place no trust in.
For me the dog has already bitten. The free software I extended to an audience I believe would show the same generosity has instead been made into a proprietary product.
The "copyright" question for me is not a question of "fairness" or ability of Microsoft or anyone else to make a product. For me it's a tool to protect my contribution from proprietary business.
Basically. I dont want the animal safer, I want it free (according to the FSF freedoms).
