Because that is how executives think. Apple brass discussed disclosing 128-million iPhone hack, then decided not to | Ars Technica
In September 2015, Apple managers had a dilemma on their hands: should, or should they not, notify 128 million iPhone users of what remains the worst mass iOS compromise on record? Ultimately, all evidence shows, they chose to keep quiet.
Are we shocked?
An email entered into court this week in Epic Games’ lawsuit against Apple shows that, on the afternoon of September 21, 2015, Apple managers had uncovered 2,500 malicious apps that had been downloaded a total of 203 million times by 128 million users, 18 million of whom were in the US.
Instead of notifying everyone of the actual breach, they only list the top 25 apps in an email, leaving users of the other 2,475 apps to their fate.
And the epic games lawsuit has provided some interesting info. For example. You can download Chrome or Firefox on a iPhone, but they are really using the Safari engine, which has some issues in that it doesn't support stuff that I want. But then Apple Knows Best, or something.
