Since everybody’s trying to think up cringeworthy analogies…
It’d be like Apple publicly advertising the Mac Studio on
apple.com as an ARM-based machine “Built for Apple Intelligence”. Someone else then builds an aluminium desktop with an ARM CPU and advertises it as “Built for ChatGPT”. Apple couldn’t reasonably call the existence of an ARM desktop in an aluminium case a commercial secret when they’d already published the underlying concept themselves.
The interesting question isn’t whether competitors can build similar products (or whether anybody trusts big tech). It’s whether any genuinely confidential information was taken and used.
