Random iPhone-using Google employees who use Google's internal cafe app are Apple customers, and they're directly affected.
Clearly that's not a terribly big deal, and you'd imagine that Google has a lower proportion of iPhone users than many companies, but it's not nothing.
They're professionally affected (they can't run internal apps as part of their job) as is good and appropriate (their company violated the rules and got cut).
They are not personally affected as they still have access to public versions of the apps like every other person in America.
