That part is the easy part to understand. The employer acted in a manner that made employees want to sue. They realized the fine print they hadn't read when joining the company gave away that right. What's happening now is about drawing attention to this so that future prospective employees elsewhere are aware of it and there's pressure on companies to stop requiring it.
That's the explicit point of protest, I don't understand why you'd characterize it as a PR stunt.
Or why you'd preface your statement with a dramatic disclaimer about cynicism that makes the thing you're portraying sound more sinister.
