> How would it blow up in their face when Apple's customers don't care?

There are multiple of different negative actions that can be taken against a company, beyond just customers refusing to buy the product.

These potential actions have the ability to cause Apple, and their employees, lots of harm.

For example, in America, one negative action that many people are taking against Apple is lawsuits (Apple has lots some lawsuits, in the past, and lost a bunch of money over it).

But, there could be many other ways to harm Apple, beyond those examples. EX negative publicity, people or companies refusing to work with Apple, and many other things.
