It’s still possible, but only with a physical Kindle device and I believe only one of the older ones. You can copy files off those devices to your PC and crack them that way.
Otherwise I’m not aware of any other method. It really sucks too as my favorite genre literally only exists in the Amazon ecosystem (small indie authors that rely on KU and so don’t publish anywhere else)
It was unfortunate to learn that work did not have the concept of semesters and you couldn’t just write off an assignment from your boss as ‘well I’ll get a zero from that one, but there’s always next semester’. They just keep bugging you about it over and over even though clearly I’ve moved on already.
Semesters were a much easier ‘reset’ than getting fired was.
