This might seem like splitting hairs, but I think it's extremely counterproductive to act like the battle for users' data privacy and sovereignty is lost just because most users can't tell the difference. I see this a lot from the other side: extremely cynical, at least somewhat tech-savvy people reacting to each new corporate abuse with an "old news" mentality as if we've already reached the endgame—if you haven't been using tails linux for at least a decade you may as well just zip up your home directory and email it to every shady tech corp and data broker you can find contact info for. These people ought to know better, and they ought to set a better example for those who don't.
This inculcated helplessness definitely hurts trust, but it also gives people the impression that a better world isn't possible—that there aren't better and worse choices for who to trust with their data and privacy. This Dropbox snafu seems to be that mindset coming back around: users won't give a shit if we imply we're sending their private files to a third party without asking, right? Lunacy.
Incidentally, I've had most of my data out of Dropbox for a while (in favor of a self-hosted solution), but yesterday was the kick in the ass I needed to cancel it for good. Thanks, Dropbox!
