After the lawyers take 80% of the cut, Apple will send out $25 vouchers toward the purchase of a new iPhone to those affected.
The only people who win in a class action are the lawyers.
First, as other people have said, your numbers are way out of whack and the class members do share the majority of the payout.
Second, what is your point? In a case like this where Apple is so ****-headed, making Apple bleed is a good enough thing on its own.
Third, these greedy lawyers, would not be kicking in millions of dollars of their own money to fund the lawsuit if they didn't think there was a very, very good chance their 15% cut would cover all their costs and reap a hefty profit. This is going to cost Apple big time.
Fourth, this is a PR disaster for Apple. How many average users will hear "if you do a third party repair to your iPhone, Apple will destroy your phone" and think fond thoughts about Apple? No average person is going to believe it's for their own good.
