Yes, Apple has overlooked the implications of adding such strong magnets to their lineup. Clearly their fault!
On the other hand I think it isn’t unreasonable to expect pacemaker companies to get rid of 1960’s technology and acknowledge that the world has turned. Life has changed since the days of the original conception of controlling a pacemaker or defibrillator via magnet.
And it’s not only electronic devices like Apple gadgets that pose a problem to these devices: When my father needed a defibrillator, it was difficult to a find a model that was approved for MRT, which was necessary for regular checkups due to his medical situation. Is this now the MRT developer’s fault that they did not consider pacemakers?
Feels like pacemaker and defibrillator companies are not willing to really progress, because the existing products sell well and they can comfortably hide behind the stance of required reliability and proven technology. Probably still using ancient Z80 processors and telling themselves they’re bleeding edge … /sarcasm
