Forgive my ignorance, why is there not much they can do and what have they tried?

Apple tried to use a side channel in their security coprocessor to detect if the device had booted out of DFU (which is part of how the exploit worked). This didn't work because people found a vulnerability in that processor itself.

My understanding is that because this is a hardware-based issue, there’s no way to release a software patch to fix it.
