It’s a good question, lots of interest in the recent announcement from apple (as always!)

Snakk provides much of its advertising into mobile apps, where 90% of mobile traffic occurs.. It appears apple’s change might only impact mobile users of its safari browser, it won’t affect in-app environments

However the MIT Tech Review prob explain the likely impact well, have a read of this.. It made good sense I thought?
