I am not surprised - the general pattern with Torvalds seems to be that he's maximally pragmatic. His problems with say Nvidia drivers aren't the fact that they're proprietary, it's that they are difficult to interface with the kernel. I have a strong impression that what matters to Linus is software that works well, so he cares a lot about the quality of the kernel and ideally wants other software to be similarly reliable.
If he judges that Claude does the best job, it'd be very much like him to use Claude. It would be unlike him to use an open program if he considers it inferior.
