It would likely be a blip in the news, and then people would move on, as usual.
Remember the Sony rootkit fiasco? People still buy Sony, and most people probably either never heard of that incident, don't remember, or don't care. Buying whatever the new Sony gizmo of the day is is more important to them.
Microsoft has had endless spyware fiascos, and people still routinely buy Windows, as long as they can play their games or run Office, that's all that matters to most of them.
Then there have been scandals like Enron, where the execs knew that they were doing something that was clearly illegal, and that their company really would be devastated if what they did was ever revealed. These "smartest people in the room" did it anyway.
Corporate history is full of just such deceptive and destructive practices. I'm not sure I'd put Facebook above that sort of thing, a priori.
I can see that happening again with voice recordings.
Your relative probably installed something and pressed "Next" through all the dialogs including the ones asking if they want to install super helpful bundled software.
But it's an interesting question: if someone credibly proved that FB was "wiretapping" on such a massive scale, would they get prosecuted? How much could they do in their own defense? Are they so enmeshed that prosecutors wouldn't bother?
Feels like a case of "unstoppable force meets immovable object".
I think you wildly overestimate how angry users get about privacy violations. For examples, Target, Yahoo, Home Depot, and Equifax have not been screamed into rubble.
So not literally everyone... but still many.
It was the second to go, just after Facebook.
For what it's worth, this public opinion backlash has not appeared with other companies: "Of course we're not working on leaked project [x]". "Look at project [x] we're working on!"
Even Facebook's own under-disclosed psychological experiments have been largely forgotten; Facebook has suffered few if any long-term ill effects from it.
is uber still the most hated company or has the magnifying glass moved onto somewhere else?
