The camera PCB was made by rpi for specific use with the rpi. The DRM chip is not part of the camera vendor's assembly. It is a separate chip placed on the PCB, therefore placed there by the PCB designer, i.e., by rpi.

There's even a kernel driver for the CSI receiver, which we paid for ((link: https://patchwork.kernel.org/patch/9951525/) patchwork.kernel.org/patch/9951525/). What you can't do is clone the official v2 camera module and use the default ISP tuning, which we also paid for.

Personally I have no problem at all with protecting the investments around add-ons like this module, if it means they continue to persue them.
I'd prefer if they gave us the full functionality of the device though - the imager is capable of global shutter but it is locked out.

That's a fair point. Perhaps when camera v3 is released they'll have the option of updating start.elf and removing the restrictions on using this hardware.
Isn't the use of the chip by the user entirely optional?
Well, it's optional in the sense that if you can find a way to use the camera with some board other than a Raspberry Pi then you don't have to use it. If you're doing the intended thing of connecting it to a Raspberry Pi, though? Not optional.
