Yeah, if this is as good as it sounds for users Facebook should have taken out full page ads explaining why they should just tap "Allow" instead of "Ask App not to track"

Really you'd think Facebook would be happy about this change, because it gives extra visibility to all the hard work Facebook engineers are doing to deliver you quality ads. Many users might not know about these efforts right now, since it all happens invisibly in the background.

This is a funny way to frame it and puts it all in perspective, exactly right.

If just telling people what is happening causes this reaction, it certainly makes you think.

99% of people don't change the default, same reason why people don't opt out. It's not really an argument in either direction.

Right, but with this change there is no default. iOS asks you, for every app, whether or not you want to allow tracking, as opposed to just silently defaulting to "allow".

I understand the default though on iOS is to have tracking enabled — but present the user with an alert to allow them to turn it off.
