What is wrong with pacemakers that they can't make one that functions
around radios and microwaves?

Lack of space for installing the faraday cage.

Pacemakers DO function around radios and microwaves.

After getting a pacemaker, I chatted with the manufacturer about RF
interference, etc.
The only concern shown was for magnetic fields, and no problems were
expected if the field was removed. I was encouraged to avoid airport metal
detectors mainly because the manufacturer couldn't be sure what kind of
contraption TSA would come up with.

RF ablation didn't affect it. The circuitry seems to be solidly designed.
