I think apples lawyers would strongly advise against them publishing teardown videos.

As well as opening up liability and warranty issues when users consider those as 'instructions' to disassemble apple devices, it could also be seen by courts in some countries as publishing the design and internal details which would weaken Apples IP protections in some places.

It reminds me that Sony provided a super clean teardown video of the PS5 at launch.

I sincerely doubt it matters in term of IP/patents. Apple might not want to deal with any of the press that could come with it, and for a corp doing nothing is cheaper that doing anything. IMHO the loss on Apple Store revenue ans hgiving je image of a brand you can tinker with outweigh any legal part.
