Your concern that companies like Meta and Microsoft are too scared to let users retrain their models is also irrelevant considering both of these companies have already released models so that anyone can retrain or checkpoint merge them i.e. Llama by Meta and Phi by Microsoft.
they release them to developers, not automatically retrain them unsupervised in their actual products and put them in the faces of customers to share screenshots of the AI's failures on social media and give it a bad name
I can't believe they waited so long to enable Proton by default lol
