I really struggle to believe that "Google" thinks this itty bitty extension that a rounding error % of their users use would have an impact on their buisness model, which was grounds to kick it off the store.
This "just" sounds like the typical story we hear so often of an overzealous "app" reviewer waking up on the wrong side of the bed and just decided to delete someone's product and/or business (which is a huge problem itself!)
One extension does not have an impact, but in aggregate across many extensions these things can make a huge difference.
The primary reason Google has Chrome and Android is to maintain ecosystem control and to continue tracking users to support it's Ad business (or reduce the threat that other browsers will diminish it's business in these areas).
