You can't have it both ways. As a library author choose MIT to encourage commercial usage because companies are afraid of GPL, but then complain that companies are actually using it in a MIT license way without contributing back.

I can find it off putting regardless. Especially since I’m not the person who released it under MIT license.

License it GPL, and it will be fed to a model as training data to recreate it copyright free anyways.

Training falls outside of copyright concerns because of fair use, so proprietary or free is orthogonal. This is how the world is currently trending.
