A colleague came across this post which was released just over a week ago:
I'm a basic Marketo user who only works with standard functionality - I even don't understand exactly how Marketo works technically. So does this mean that tracking user activity on Apple devices could become a lot harder? Or impossible? And what if Chrome does something similar? Or does this not affect Marketo at all?
Be interested in opinions from the community - I couldn't see another post regarding this since the new policy was released.
I won't get into a long discussion of the Why here. (You can watch my blog for that.)
The spirit of Munchkin tracking is merely first-party tracking -- and thus is not in violation of the WebKit TPP and similar policies. But the letter, i.e. technical implementation of Munchkin, is in violation because it's sending beacons/pixels to a 3rd party. At some point, Munchkin is going to need to operate on a subdomain of your first-party domain, rather than via munchkin.net & mktoresp.com.
