Or, you know, it might be that Taylor, oh, I don't know, TRUSTS Dragon not to screw her over?
And from her viewpoint she would be perfectly correct to do so. Sure, the PRT or any other legal authority could order Dragon to screw her over, but she doesn't know that, and more importantly, why would they kill the golden goose?
From their viewpoint, Taylor appears to be a tinker whose creations can be mass produced.
This is what is known as 'The Holy Grail' from the PRT's perspective.
I expect Carol's little tantrum to backfire on her horribly once that fact sinks in.
