It's high time this has happened. Certain large tech companies with abusive cultures have been open secrets for years (Ballmer-era stack ranked Microsoft, PIP culture at Amazon). But Apple's secretive, authoritarian nature has kept it under wraps for decades.

Apple is a huge corporation and there is a large degree of variation within it. But when things are toxic there, they can get very toxic. Middle managers can have a lot of leeway there, and HR is about as powerless as you can imagine. There is not much room for dissent against decisions there, forget "think different". The product schedule is all-important and can also be very stressful to work under. It's a situation that Apple employees can only sympathize with one another, but not much else.
