I think the reason is mostly technical, but also legal. The ICD3 uses a
large FPGA to implement the high-speed USB interface. It may be
economically inviable to make small batches because of the high cost of
the FPGA. Besides, I don't think Microchip has published the FPGA
configuration file or the PIC firmware.

If the FPGA boots from an external memory then this is a no-issue, but
there are FPGAs with protected internal memory.
Also, the firmware updates may be encrypted and the boot-loader in the
PIC may be well secured.
