Isn't the case that you can already opt out, as I do, by just visiting facebook.com using Safari and AdGuard on iOS instead of installing the Facebook app? And doesn't this very public controversy now mean that everybody knows this? I'm not defending either side but just pointing out that we already have the choice.
This is talking about apps that use the Facebook SDK, which allows Facebook to track you across apps (and websites). This includes apps such as Dropbox, Spotify, Yelp, Duolingo, and many others [1].
Thanks for clarifying. And that article was informative too.
Understanding this further does make me less hesitant to side with Apple here. I use Duolingo (spinoff of my alma mater), and I understand that they depend upon ads to fund their business. But my understanding is that user consent is only needed to get the unique advertising id. So apps just need to be more creative with contextual ads, and get to know their users directly instead of depending on Facebook.
