My understanding is that it's only people who were employees of these companies at the time, though it's easy to argue that anybody in the tech industry was indirectly affected.

I.e. the salary paid to these employees influences the salary expected to be paid to people doing the same at a different company. Especially considering the size and importance of the companies involved. Strangely, I haven't seen this discussed much in articles about this scandal. (of course I say that as someone who did not work at any of the involved companies)
